There’s something unpleasant going on. All across Europe, far-right parties are popping up, spreading a message eerily similar to one that you could have heard in Italy and Germany in the early 1930s. Different parties in different countries have their own individual policies but the common denominator is an anger at the current state of affairs. They demand an immediate stop for spending money on welfare to people of “foreign origin”. Borders should be closed, immigrants should be expelled or at least closely supervised and all international aid should be stopped at once. Basically, it’s a message of intolerance.
On a smaller scale, people in all walks of life seem to feel unjustly treated, as if they somehow have missed out on something. There’s a prevalent sense of envy and jaundice, of seeing oneself as a victim of some kind of conspiracy. Everyone else seem to be much better off, and they most surely don’t deserve to. It can be as simple as someone having a later model of a smartphone than you do, or what seems like a better job. Or perhaps a newer car or a bigger house. Regardless of the details, it comes down to haves and have-nots. And if we lived in a society where that could mean the difference between life and death, those things would matter. But in the modern post-industrial countries of Western Europe, we don’t. We have what we need. Our children get fed and educated, we all have clothes to keep us warm and places to live to keep us dry. And the few unlucky ones that don’t should be able to rely on a well-developed welfare system to help them out.
I know, it’s not a perfect system. People who need help sometimes don’t get it. And sometimes people who don’t need help get it anyway. But on the whole, it shouldn’t impact on your life or hinder you from making it a good one. So that sense of envy – which is most likely a left-over function from past times, when life was truly rough – is now more or less obsolete.
But that doesn’t really matter. The green-eyed envy and delusion of being subjected to government-made plots and conspiracies manifest itself as anger and frustration, which in turn easily and quickly escalate into a hot white hate, blinding us from any kind of logical arguments and reasoning. And suddenly we start to long back to simpler times, when all was good and people worked for a living (and with job titles we actually understood the meaning of). This in turn will promote conservative values, like the importance of traditional family structures (ideally banning all those newfangled PC alternative lifestyles all together) and stopping the immigration to finally get rid of all those multicultural influences.
And before we know it, the only party we can vote for is one of the new ultra-right single-issue ones. And that’s exactly what we see across Europe at the moment. From UKIP in Britain, SD in Sweden and NPD in Germany to Fiamma Tricolore in Italy, Front National in France and Svaboda in Ukraine, far-right extremist parties have gained momentum in the last few years. Even though they are still mostly in minority, they are loud and attention-hogging and their presence highlights that people more and more let their anger guide them where to put their votes.
The missing piece
What most traditionalists seem to miss, however, is that things weren’t all that different in the past. We’ve never had that traditional and simple society that everyone seem to remember so fondly, with a single culture, consisting of a single, racially coherent people. We’ve always had immigration and we’ve always been multicultural. And thank goodness for that, or we wouldn’t be able to enjoy the richness of culinary delicacies that are almost without exception imported from abroad – even (or perhaps even particularly) our treasured national dishes. We would not be speaking the languages we are speaking without the countless influences from dozens or more foreign tongues. Our multicultural heritage is what makes us us.
As a species, we have always been a melting pot of ideas, cultural memes and linguistic influences. That is what has ensured that we survived where the other species of humans did not. We absorb new trends and phenomena at a speed and with a delight that is unprecedented in the history of evolution. We are multicultural masters, picking and choosing the best from every new society we encounter. It’s our speciality and the key to our success. But I’m aware that I’m preaching to deaf ears. If anyone who feels threatened by the current state of affairs would end up on this blog and read this post – a rather unlikely scenario, I admit – they would no doubt dismiss it all as stupid socialistic propaganda at worst or as well-meaning but horribly misguided advice at best. The blind hate mentioned above has… well, blinded them.
The stench of intolerance
For me personally there’s an additional aspect to this topic however. I find intolerant people truly unappealing – revolting even. Intolerance disgusts me. The selfishness of the intolerant person make them somehow look smaller, like shrivelled up remnants of something that was once human but what has now been reduced to something much less. Something sub-human. Not from belonging to the “wrong” class or race or culture but from having willingly rid themselves of the most human quality of all: empathy. And in the wake of a lack of empathy, a range of unsavoury concepts eagerly awaits to fill its space: victim blaming, stereotyping and scapegoating, all fed by the celebration of ignorance, disrespect and contempt.
To be clear: we all have the full range of human emotions. We all sometimes feel envy, contempt or hate. Sometimes. And that’s the key. Without wanting to sound like a Star Wars fan, if we give in to the dark side it will consume us. All that will be left will be the sad remnant of a once proud, thinking, feeling and empathic human being: an empty husk, filled only with the smelly vapours of mistrust, hate and intolerance. The choice is ours and it’s a continuous one. Every day, every time we interact with another human being, we have to decide: “shall I be a real human being, making use of my full range of emotions and mental faculties, or shall I be an intolerant asshole?” Don’t be an asshole.
Contemplate, if you will, the picture above. It’s most likely a familiar sight, have you ever caught a glimpse of a nature documentary on the telly: the African savanna. Zebra, wildebeest and buffalo graze away in the hot sun, and we sense the presence of lions, poised to attack them at any time.
Imagine then, if such is your pleasure, the same scene with just one component missing: grass. Without the tiny green leaves of the plants from the Poaceae family, there would be no savanna but rather a thick forest of thorny acacia trees or perhaps a hot and arid desert. No giant herds of zebra and wildebeest. No lions to stalk them.
A world before grass
It might seem like grasses have always been around, that they’re somehow a very ancient group of plants, but in fact they’re quite a recent* addition to the planet’s collection of biomes. Even though the earliest species of grass appeared some 60 million years go – just before the end of the era of non-avian dinosaurs – they were just a scarce and limited selection of plants growing near rivers and lakes.
In those pre-grass days, the world was a different place, covered by thick forests and deserts. No open plains full of grazing animals, no evolutionary race between swift herbivores and even swifter predators. It was at once a slower world, with most animals walking leisurely about and a more violent one with ambush predators lying in wait in the lush undergrowth.
And this was the state of the world for hundreds of millions of years. From the ancient fern forests of the late Devonian 360 million years ago, through the swampy oxygen-rich forests of the Carboniferous, the vast deserts of the Permian and Triassic, the lush conifer forests of the Jurassic to the first flowering plants of late Cretaceous, forests gave way to deserts and desert in turn were overgrown by forests. Not until the end of the Oligocene, some 20-25 million years ago, did grasses start to spread to more arid plains and form the steppes, savannas and prairies we see today. And it took another 15 million years before the modern C4 grasses like maize, millet and sugarcane started to make an appearance.
A dangerous opportunity
This might all be fascinating on a theoretical level, but there’s more to the story of grasses than a study in biome evolution. The spread of grasses and the formation of wide and open grasslands changed the adaptive path for many animals, from antelopes and horses to carnivores and birds. But there was another group of animals that was also affected, a small insignificant family of primates suddenly finding themselves exposed in the open: hominids.
Our ancestors got it rough. Not only were they small and defenceless, they lost their natural habitat and had to make do in a very competitive landscape, filled with powerful and dangerous herbivores like buffalo, rhinoceros and elephants and hunted by fast and furious predators like lions, leopards and hyenas. This, in combination with the constantly changing climate, forced us to develop tools and weapons and get us to rise up on our hind legs and become bipedal.
But as harsh as it was, the new grasslands also promised something new: a huge hunting ground full of game and lots of grass seeds and roots to eat. And as the savanna expanded north and met the Mediterranean Sea, so did our human ancestors, spreading on to the Middle East and then east into Asia and north into Europe.
Our green little friends
The story doesn’t end there either, though. Not only has grasses changed the face of the Earth and facilitated the evolution of our own species, they have also been instrumental in taking us from a few thinly spread hunter-gatherer tribes to being the most widespread mammal in the world, sporting the most advanced societies the planet has ever seen.
Some 10,000-15,000 years ago, just at the end of the last glacial period, we were getting a bit crowded. There were tribes of humans all over Europe, Middle-east, Asia and Africa and we were running out of places to gather food. Something had to be done.
Cue the agricultural revolution. Instead of walking miles and miles to find the herbs, roots and seeds we needed to stay alive, we started growing them around where we lived. And the main thing we grew was different types of grasses: wheat, rye, barley, millet, rice, and maize.
It wasn’t a revolution without casualties however. Rather than providing us with a reliable source of food, the first cultivated grasses were prone to bad harvests which made sure that starvation and malnutrition became a regular occurrence in human societies. In fact, it got so bad that the average life expectancy was dramatically lowered and the people who survived to adulthood grew up to be significantly shorter and weaker than our hunter-gatherer ancestors. Essentially, agriculture was making us frail and sickly.
But we persevered – most likely because there was no real alternative; we’d effectively run out of space and had to make our own food from now on – and fast-forwarding a few thousand years to present day we’re much more accomplished farmers. We now rely on a range of grass seeds for our daily food and as a result they make up the absolute majority of what we consume; be it in the form of noodles, rice, porridge, bread or pasta. As chance would have it, we turned out the only grass-eating ape** on the planet and a very successful one at that. Grasses surely are our green little friends.
* As always, ‘recent’ is a relative term, and in context of speciation and evolution usually refer to some million years but fewer than a hundred million.
** We might be the only grass-eating ape, but there is another primate that’s also a graminivore: the Gelada, an East African highland baboon. They eat their grasses raw, however. As we cook our grass seeds, we get more nutrition out of them and are hence better than them and can feel appropriately smug and superior.
You’re at the grocery store, doing the weekly shopping when you come over a little peckish. Considering something for the road, you see a packet of Twinkies:
It seems an innocent enough treat, if a bit calorie rich. But on a hunch you turn the packet over, start reading the label and find the following:
Enriched Wheat Flour (ferrous sulfate, niacin, thiamine mononitrate, riboflavin and folic acid), sugar, corn syrup, water, high fructose corn syrup, vegetable and/or animal shortening (containing one or more of partially hydrogenated soybean, cottonseed or canola oil, and beef fat), dextrose, whole eggs, 2% or less of: modified corn starch, cellulose gum, whey, sodium acid pyrophosphate, baking soda, monocalcium phosphate, salt, cornstarch, corn flour, corn syrup solids, mono and diglycerides, soy lecithin, polysorbate 60, dextrin, calcium caseinate, sodium stearol lactylate, wheat gluten, calcium sulfate, natural and artificial flavors, caramel color, sorbic acid, E102 (Yellow 5), E129 (Red 40)
“Whoa. That’s a lot of ingredients.” you say to yourself. “And how do you even pronounce ‘sodium acid pyrophosphate’? Or ‘calcium caseinate’? And that ‘thiamine mononitrate’ sounds really nasty. Better off picking up some fruit and have a healthy natural snack. Bananas are good and filling, I’ll get some bananas instead.”
All natural banana
Bananas are a good tasty snack. And I won’t mention the highly unnaturally selection having being performed upon it to end up with the cultivated version of the wild banana berry*.
But consider the ingredients list for a natural banana, if such a list was legally required:
Water (75%), sugars (12%) (glucose (48%), fructose (40%), sucrose (2%), maltose (<1%)), starch (5%), E460 (3%), amino acids (<1%) (glutamatic acid (19%), aspartic acid (16%), histidine (11%), leucine (7%), lycine (5%), phenylalanine (4%), arginine (4%), valine (4%), alanine (4%), serine (4%), glycine (3%), threonine (3%), isoleucine (3%), proline (3%), tryptophan (1%), cystine (1%), tyrocine (1%), methionine (1%)), fatty acids (1%) (palmitic acid (30%), omega-6 fatty acid: linoleic acid (14%), omega-3 fatty acid: linoleic acid (8%), oleic acid (7%), palmitoleic acid (3%), stearic acid (2%), lauric acid (1%), myristic acid (1%), capric acid (<1%)), ash (<1%), phytosterols, E515, oxalic acid, E300, E306 (tocopherol), phylloquinone, thiamin, E101, E160a, 3-methylbut-1-yl ethanoate, 2-methylbutyl ethanoate, 2-methylpropan-1-ol, 3-methybutyl-1-ol, 2-hydroxy-3-methylethyl butanoate, 3-methybutanal, ethyl hexanoate, ethyl butanoate, pentyl acetate, E1510, natural ripening agent (ehtylene gas)
That list is even longer than the Twinkie one. And just as full of scary-sounding things like ‘tocopherol’ and ‘2-hydroxy-3-methylethyl butanoate’. Also, ‘ash’? Really? And ‘ehtylene gas’ – isn’t that what they run those welding machines on?
Now, I don’t want to scare you off ever eating bananas again – that’d be silly. Rather, the point I’m somewhat laboriously making is that chemistry is complicated. And organic chemistry even more so. Our naturally occurring foods often contains more weird chemicals than our man-made varieties.
The Frankenstein syndrome
There seem to be a prevalent mistrust of anything synthetic. A fear of plastics, chemical additives, man-made fibres, metallic alloys and other manufactured compounds. I’d like to label it a phobia (chemophobia would be the correct term), but perhaps it’s not a completely groundless fear? We’ve after all heard about countless incidents involving man-made chemicals and substances: factory emissions, illnesses from synthetic materials used in buildings and fabrics, allergic reactions to newly discovered chemical compounds and so on. It does really seem like whenever we invent something, something bad follows.
It’s called the Frankenstein syndrome – a fear of our own creations – and it seems to be widespread in modern society. But why are we so ready to mistrust new inventions? Are we really that bad inventors/scientists/chemists that we constantly and over and over again release monsters into the wild?
It could be argued that this phenomenon is just a variant of the old Luddite hatred of everything new, but I think there’s more to it than that. In addition to the mistrust of the unknown – which, to be fair, is pretty reasonable – there is a fear of loss of control. Once we’ve created something new, we effectively let go of it and let it run rampant. And even though the creator(s) usually swears by their new product and assure us it’s benevolent, observers from the outside of the lab are less convinced.
And so the mistrust and fear start off rumours and urban myths. Like the ones about the Brilliant Blue FCF colouring agent used in certain sweets. Rumours would have it that the – rather unnatural-looking and therefore surely harmful – food colouring induced hyperactivity in kids that had enjoyed some blue M&M’s. And even though numerous studies showed that this was not in fact the case, those rumours refused to die and parent kept on going through the bags of M&M’s to rid them from blue ones before their kids got their hands on them.
There is also an element of denialism at work here. Healthy living is now a fairly common lifestyle choice and people striving to eat organic food without artificial chemicals. This is all a Good Thing, but the notion that we could somehow live chemical-free lives is a false one – even with the rather incorrect definition of ‘chemical’ meaning ‘synthetic’. There is no place on Earth today that is not already affected by man-made chemicals. The water, air and soil is everywhere treated with a cocktail of assorted compounds, ranging from the beneficial to more harmful ones.
Of course, the level of artificial contamination will vary somewhat and the choice to add your own in form of synthetic fertilisers and herbicides/insecticides/fungicides will affect this level further. But be in no doubt – there are no produce to be had on this planet that are free from artificial chemicals.
Ok, so what is my point? Should we panic or should we just resign and give up? Is it the end of the world or is it nothing to worry about?
Well, neither really. Artificial chemicals might not be the end of the world as we know it and they are certainly not automatically evil, but it would make sense to keep an eye out. Some of the chemicals we’ve released have been rather nasty indeed, especially when in form of different metals. We still remember the effects of DDT and mercury compounds and even today PCB is present in the environment. Clearly a more stringent view on how we test man-made chemicals before releasing them into nature or put them in our food has been required.
But let’s not go overboard. A lot of what we see in the ingredients list for our groceries are compounds readily found in nature. As always, more knowledge about what’s what and what could potentially be harmful is required. Combined of course with a will to actually learn and accept new findings. So we need a little less of the “I don’t care what they say; I’ll never trust these additives!” or “All newly invented things are always great and should be welcomed with open arms” and more of “Ok, let’s see if there are any good studies on this.” Less dogma and more research.
After all, knowledge is a good thing. Make sure you get yours; that’s an additive we cannot do without.
I’d like to thank James Kennedy for the inspiration for this post – and for painstakingly listing the ingredients for a bunch of natural products.
* Just for the record – this is what a natural wild banana berry looks like:
Every morning I get out of bed and stumble into the kitchen. There I make myself a mug of hot dark Kazaar lungo. The first sip tastes almost like hot smoke, the second is already softer, smoother. Almost instantly I can feel the buzz: my brain switches into gear and I start to function on a higher level. I’m awake.
1. Caffeine uptake and half-life
Unfortunately, the instant wake-up effect of coffee seems to be a myth. Depending on your metabolism, it takes up to 45 minutes for the caffeine in coffee to enter your blood stream. So the effect I’m experiencing is either a placebo or it’s to do with the bitterness of the coffee itself. This also means there should be no issue taking a cup of coffee right before bed time, as long as you fall asleep before the effect of the caffeine kicks in. In fact, I often take a strong coffee before I go to bed to help me sleep. And as to how long it takes for caffeine to leave the system, its half-life is between 5 and 8 hours. So if you’re not used to coffee, the effects of a single cup could stay with you most of a working day.
2. Origin and evolution
Caffeine can be found in a number of plants, either in the seeds (like coffee seeds or ‘beans’, the berries of guarana or the kola nut) or the leaves (like in the tea-plant). Evolutionary, caffeine has evolved to act as an insecticide, paralysing any larvae that feeds off the plant. It also seem to work as an inhibitor for seedlings of the same species, making sure no other plants grow too close in order to avoid competition for resources. Additionally, caffeine seem to trigger a reward behaviour in honey bees pollinating the plant, encouraging them to revisit similar plants, which would increase the probability of successful reproduction.
3. The colour of caffeine is – clear?
Rather counter-intuitively, caffeine is actually clear when mixed with water, so the colour intensity of the coffee or tea is a poor indicator as to how much caffeine it contains. For instance, dark roasted coffee contains less caffeine than light roasted, due to the fact that the roasting process removes some of the caffeine. And pale tea often contain as much – if not more – caffeine as black tea.
4. Tea vs coffee
Speaking of tea: you’ve probably heard that tea contains more caffeine that coffee. This is strictly true, if measured by dry weight, but as a prepared beverage coffee contains many times more caffeine than tea. Which – if you think about it – you already knew from the effect of coffee compared with the much weaker effect of tea.
5. Kola, cola or coke?
Just like coffee is originally from Africa, so is the kola tree. The nuts of that tree contains caffeine and has traditionally been chewed to produce a stimulant effect.
More recently, extracts from the kola nut have been used in certain soft drinks to give them a similar effect (and also possibly create an addition to the product in the consumer). However, coca leaves are no longer used, so perhaps one of the more known brands should consider changing the name?
I’ve written a post on chocolate before, where I explained all its amazing benefits. In addition to all its other qualities, dark chocolate also contains quite an amount of caffeine, as much as coffee in fact.
The effect is however reduced due to the combination of theobromine and theophylline that are present in relatively high levels. This is why you don’t get the same buzz from chocolate. (What? No, sorry. That buzz is the effect of all the sugar found in chocolate. I’ll save the pros and cons of sugar for another post.)
7. Side effects
There are several misconceptions about the effect of caffeine (and coffee in particular) on our health. One is that drinking too much coffee will cause gastric ulcers, and that we should limit our intake to only one or two cups a day.
This is false. Gastric ulcers are caused not by coffee but by the bacterium Helicobacter pylori, something the Australian doctors Barry Marshall and Robin Warren proved in the 1980s: Dr Marshall deliberately drank a concoction containing this microbe and within days, he had developed several gastric ulcers, without drinking copious amounts of coffee.
8. Health benefits
In fact, rather than being detrimental to our health, caffeine seem to offer some protection against a range of diseases, including Parkinson’s, Type 2 diabetes, liver cirrhosis and certain types of cancer. You would need to consume a lot of coffee to get these effects though; more than 4-5 cups of coffee per day.
9. Loo breaks
Another common misconception is that caffeine is strongly diuretic, and that you will have to run to the loo all the time if you drink tea, coffee or cola drinks. The truth is that caffeine is only mildly diuretic and only in people who are not used to it. One of the amazing things about caffeine is that all the side effects (sleep disturbances, nervousness, minor muscle tremors etc) wear off as you get used to the drug. The benefits however (alertness, increased concentration capabilities, reduction of physical fatigue etc.) all stay with you, regardless of how long you’ve been using caffeinated drinks.
Even so, as with most alkaloids, caffeine is toxic to human beings in high enough concentrations. It would however take 80-100 cups of coffee to achieve a lethal dose. The risk of overdosing on coffee is therefore rather remote, but there has still been at least one reported death attributed to caffeine: a man suffering from liver cirrhosis overdosed on caffeinated mints.
11. Memory enhancement
But I’ll end this list with a new discovery: it would seem that caffeine will help us with memory consolidation, i.e. the process of converting short-term memories to long-term memories. In a recent study, people who consumed two cups of espresso just after a memory test outperformed the placebo group. There seem to be a sweet spot at 300 mg, though, so don’t overdo it. Two cups of espresso is just enough – no more, no less.
The dark mistress
Overall, caffeine seem to be quite a drug. No real side effects (and the minor ones that do exist, fade away over time), and several mental and physical benefits. But drinking tea or coffee isn’t down to logic; it’s a life style – a passion, even. Once we get over the bitterness of the dark mistress, we just can’t get enough of her. Which in the cold light of logical thinking might be a drawback, but I really don’t care. Give me another mug of that strong dark hot stuff.
A while ago – several years ago, actually – I wrote a post on electric cars, bemoaning the lack of market penetration, even in the 21st century. It was sort of a prequel to the post The future isn’t what it used to be, where I commented on the lack of technical advancement. There’s another side to these two stories and that’s the one about autonomous vehicles, a.k.a. self-steering cars.
Just like electric cars, self-steering cars have been around for a long time, albeit in a limited sense. Already in the 1920s, there were successful experiments with remote-controlled cars driving in heavy city traffic. But of course the computer power to create fully autonomous cars didn’t exist back then, and instead the research was focusing on getting autonomous cars follow magnetic or electric rails hidden in the streets. This railroad car technology never took off, due to the potentially astronomical costs of amending all the roads in the world with guide rails.
Even with the replacement of guide rails for electronic devices to detect road and lane edges in the 1960s, the cost was still too high except for limited field trials, and it wasn’t until 20 years later we got the first hints at cars being able to detect the roads and lanes all by themselves.
And now, 30 years on, we have fully autonomous cars driving in real live city traffic on a daily basis. Companies like Mercedes-Benz, Volvo, Volkswagen, Ford, Toyota, Audi, BMW, Nissan and GM are all currently testing driverless cars. And of course we have the famous Google cars.
And gone are any needs to have amended roads with sensors and guide rails. Modern cars know what a road is from looking at it, and know how to stay on it. They also know how to keep their distance from surrounding traffic and how to navigate intersections and multi-lane highways. They do this with higher precision than human drivers and at higher speeds.
In fact, as the technology has matures so quickly (relatively speaking), governments around the world are finding themselves with outdated traffic legislation and are scrambling to catch up. Germany and UK have already passed laws that allow driverless cars to operate in traffic, with the owner of the car responsible for any accidents – even if he or she wasn’t driving at the time.
So what will the future bring? When will we be able to buy our first driverless car? And will we want to?
Well, the benefits of autonomous cars are numerous. First and foremost it will almost certainly cut down road traffic accidents by at least 95%. With high precision driving systems (that never get tired, lost, frustrated, drunk or sick), aided by radar and infrared sensors (allowing them to see in the dark or fog) we would soon enter a period of time where people getting hurt or killed in traffic would be major news. It would be more common to be hit by lightning or winning the lottery than being part of a car crash.
Secondly, it would make traffic much smoother. Human beings aren’t exactly renowned for the logical thinking – and this is especially true when driving – so much of the traffic congestion problems we experience in cities today is down to irrational driver behaviour. Not so with autonomous cars. They will let other vehicles in, they will keep safe distances and reasonable speeds, they will know which routes to avoid at certain times of day and they will communicate with each other in a polite and relaxed manner.
Thirdly, we have convenience. Apart from being able to let go of the rather stressful activity of keeping a metric tonne of heavy machinery on the road at high speeds, we would be able to have our cars pick us up at home and drop us off at work and then go somewhere else to park for the day. No more need to look for parking spaces or waiting for the car to heat up and defrost on cold winter mornings. And, we wouldn’t have to worry about having had a drink for dinner, or being too young or old to drive, or suffering from a disability of some sort. The car would take us where we need to go.
And lastly, it’s the financial aspect. Even though self-steering cars will no doubt be prohibitively expensive at first, prices will soon drop and we could expect autonomous cars to become cheaper than manual cars at some point in the near future. Add to this the reduced need for insurance and the optimal fuel-economy of autonomous cars and you’re sitting on a winner. In the bigger picture, society at large will also benefit, since costs for road traffic accidents and their related human traumas add up to astronomical amounts on a yearly basis.
There are however a few obstacles on the road (no pun intended) to that bright new future. And they’re not related to technical limitations – undoubtedly the technology needed for autonomous cars will become better, cheaper and smaller over time, but even what we have today is perfectly adequate.
No, the problem is more one of human nature. It’s our own inbuilt fears and hangups that will prove to be the most difficult obstacle. And for once I’m not talking about the Luddite syndrome of hating and fearing everything new (that’s another post). No, this time it’s more about loss of control.
Humans are an industrious bunch of monkeys. We keep on inventing more and more advanced ways of staying ahead of the game, of keeping ourselves safe and alive. Fire, stone tools, fur clothes, huts and canoes. And lately interstate multi lane highways, high-rise buildings, water closets and streamed high-definition IP-based television.
But the downside of all our inventions is that it makes us think we’re in control; that we somehow can control life. And that feeling of control is something we don’t want to give up. We assume we always know best. We really are the most arrogant primates on the planet.
This could have an effect on the uptake of self-steering vehicles. Even if autonomous cars will be better drivers than even the most seasoned and experienced rally driver, we will harbour an inbuilt mistrust towards them. A machine could never really drive a car, surely? How would it know what to do if something happens? It would never be as good a driver as I. Or – what if something goes wrong? What if it malfunctions? Then we’ll be stuck in an out-of-control car, running down the streets at rush hour at 90 mph. It’ll be a nightmare!
Yes. It certainly would. But let’s think about it factually: how many airplane crashes have you heard or read about that were caused by autopilot failure? And how many that were contributed to human error? Granted, driving a car is more difficult than flying an airplane, but even so: people being distracted or reacting too slow or being just plain drunk is the main cause of road traffic accidents. Not the cruise control running amok or the automatic break system failing.
Like it or not…
In the end it won’t really matter. Technology have a tendency to march on regardless of any concerns for safety or lack of freedom. Already this year, Mercedes will be selling their S-klasse, with autonomous steering, breaking and lane control systems. Volvo and Ford will follow with their semi-autonomous cars and next year both Audi and Nissan will join the ranks, closely followed by Toyota and Cadillac. And within six years, we will see the first fully autonomous vehicles be available on the market, with Mercedes-Benz, Volvo, BMW and Nissan selling completely self-steering cars in stores around the world. Within five more years, they will be joined by Ford and Daimler.
So it looks like there will be a dozen or so different models of autonomous cars driving around in our everyday traffic within a few years. We will no doubt hate them at first, as they will drive carefully and keep to the speed limits. We will also hate them because they will be very expensive cars and we would also like to be able to afford one. But after a few years, these feelings will most likely fade away, and it’s not unlikely that if you buy a brand new car in 10 years time you will opt for the more convenient self-driving one; if nothing else because of the huge savings you’ll make on the insurance premium.
And fast-forward another 10 years and we can expect to find old-fashioned manually steered vehicles only at the bottom of the range. Instead, all mid-class vehicles will be autonomous and some will boast new trendy features like downloadable driver profiles, so that you can be driven around by famous rally or racing drivers. Or – if you prefer – perhaps a boy-racer profile? Or a senior citizen one? Or a distracted parent one? Sky’s the limit…
Either way, we will have gotten so used to the convenience and safety of autonomous traffic that we will start lobbying for a more extensive and thorough driver’s test programme for those who still choose to drive manually. Within a few more years, a driver’s licence will be as costly and rare as a pilot licence.
The future is bright, the future is now
No doubt my predictions in this post will be wrong. Predictions about the future always are. Mostly because they’re too conservative or too linear. In the 1980s, no one could even imagine the socio-economic impact of the internet. Just like no one in the early 1900s would have been able to predict the meteoric rise in motorised traffic.
But one thing is pretty clear: some years from now, when we’ve gotten old(er), we will most certainly be able to rant on about the good old days to our grandchildren. The good old days when we were still allowed to drive, and cars would still run on highly carcinogenic fossil-based fuels, like petrol. Or diesel, even.
And our grandkids will no doubt roll their eyes, stop pretend to listen or care, get into their chic fuel-cell powered autonomous personal vehicles and drive off, somewhere far far away from your grumpy old self.

It’s early morning. A thick fog is wrapping the cobbled narrow street in a translucent cotton, softening the appearance of grimy buildings and filth-ridden gutters. A group of people are quickly but quietly moving up the street towards a big red-bricked building. They stop in front of a wide double door, built from pale solid wood. One of the men raises an axe and smashes the door open. The mob storms the building and starts destroying the delicate machinery inside. Soon, only splinters and bent and distorted lengths of steel remains where once stood one of the finest examples of technological progress made in over 200 years: the automated power loom. The Luddites have struck again.
In hindsight, it might seem a bit foolish to have tried to stop the progress of industrialisation by chopping up some old machinery with an axe, but humans aren’t exactly rational creatures (see The limbic society) and tend to react emotionally to most situations.
Cue present day. A field of golden wheat, swaying slowly in the soft wind. The early morning sun has just touched the top of a hill on the other side of the valley. A group of people are quickly but quietly positioning themselves along the downwind edge of the field. On a given signal, they set fire to the tall dry grassy strands. The fire spreads rapidly, engulfing the wheat. Soon, only scorched earth and charred stumps remains where once stood one of the most technologically advanced feats in the history of mankind: the genetically modified organism or GMO.
GMO – a quick background
Now, about GMO: even though biotechnology is a fairly modern concept, the process of genetically modifying organisms to suit our needs and fancies is nothing new. We’ve been doing it ever since we cultivated the grey wolf some 10,000 years ago. But we’ve been forced to do it old-school: look for traits that we think would be of benefit to us (if not the organism itself) and select upon them. Over years, decades, centuries and millennia we have managed to create a wide range of unnatural beasts and abnormal crops, all by using controlled breeding.
What’s different now is that we for the first time have access to the genome itself. Instead of looking for how genes express themselves in the form of their parent organism’s plumage, colour or size, we can now modify them directly, either by borrowing traits from other organisms or by tweaking the genes themselves. By injecting the new genes into our target organism (on egg cell level) we can then increase an animal’s resistance to certain pathogens or increase the yield of a crop. This would then reduce the need to use antibiotics or fertilisers and would therefore help produce higher quality food for less money.
As hinted in the introduction, people aren’t all that keen on genetically modified organisms. The reasons for this seem to group together in four different arguments: terrorism, religion/ethics, invasion and health.
I’ll start with terrorism. With biotechnology we have the possibility to create new and previously unknown biological weapons and disperse them on the enemy. The population in that country would then quickly get infected and perish from this synthetic superbug.
While this is a theoretical possibility, it’s not really a practical one. It would be much easier to just use an existing virus or bacteria than to create a new one. And even then, the lack of control over how the disease will spread makes bio-terrorism even more uncontrollable than nuclear terrorism. So in short, yes, it would be possible but it could as easily turn on you and your family as on your enemy.
Next up is religious and ethical arguments. I won’t bother with the former – not a lot is allowed according to most monotheistic religions anyway, including banking, pork chops and alcohol consumption – but I will have to say something on the latter. From an ethical point of view, biotechnology is indistinguishable our current breeding programmes. We alter nature to fit our needs, with little or no concern of the welfare of the organisms themselves. Lately, we do seem to have started to care more about animal welfare (although mainly pets), which is of course a Good Thing, but regardless, bioengineered organisms should fall under the same regulations as any other creature. Which it does and all should therefore be catered for*.
Invasive species. Now this is a big one. It’s well-known that the introduction of foreign species into existing ecosystems is usually less than favourable for native species, like when the European rabbits were planted in Australia or the Japanese kudzu-vine spread into the wild in USA. The threat that a genetically enhanced organism lets itself loose and out-competes the wild fauna or flora is a real one. So far – even though several GMOs have managed to spread in the wild – nothing like this has happened. But we need to monitor the situation carefully and make sure we don’t inadvertently create a species that will become a pest. (There are safeguards in place, like suicide-genes and such, but if life and evolution has taught us anything it’s that things constantly change. The suicide genes might devolve, or lose their efficiency for a number of reasons. It would be foolhardy to rely solely on emergency shutdown mechanisms.)
And finally health. This is the argument most widely used against GMOs, and especially GMO crops. It has been stated by activist groups that GMO food could be bad for your health, either directly or through long-term exposure. A plausible mechanism for how that could possibly work has yet to be suggested. Especially since GMO food chemically is no different from other food.
Also, we have been using GMO food for 30 odd years now and no apparent epidemic of related health problems has been detected.
The only possible mechanism for harming human beings would be to deliberately introduce a gene that produces some kind of toxin. And even then it would have to be produced in high enough concentrations to harm us, which would mean precious energy that could have been used to increase the yield would have to be reallocated for expensive toxin production. The resulting crop would perform very poorly in the fields compared to other, non-toxic, varieties.
Although there are issues with genetically modified organisms, they’re mainly to do with the potential threat of creating new pest species that could potentially harm the local ecosystems. However, in that scenario, it’s worthwhile to remember that GMOs rarely turn out to be the super-organisms that everyone fear. Even if sporting a modified gene here and an enhanced gene there, they rarely perform better in the wild than the species with a few million years of evolutionary adaptation under their belt.
You might question – and rightfully so – what the point of GMO crops is, if they don’t perform any better than the regular selected crops. Actually, they sometimes do, but we’re still in the process of trying to figure this biotechnology thing out. We have managed to produce crops that express some beneficial traits, but it has not been as easy as we’ve hoped. The potentials are promising but getting there might take some time. But obviously, this should warrant more research to be done, not less.
And when it comes to health concerns, we need to remember there’s no magical ‘natural’ substance or medium. Just because a gene has been modified by us and not nature, it doesn’t make the organism somehow completely foreign and less natural. It’s still the same chemicals as in non-GMOs, and the GMO crops still contain all the regular stuff like dietary fibers, carbohydrates, fats, proteins, vitamins and minerals. Or as the European Commission Directorate-General for Research and Innovation would have it:
“The main conclusion to be drawn from the efforts of more than 130 research projects, covering a period of more than 25 years of research, and involving more than 500 independent research groups, is that biotechnology, and in particular GMOs, are not per se more risky than e.g. conventional plant breeding technologies.”
So to conclude this – all too long – post: GMO food is no more dangerous to eat than food from crops refined through selective breeding. And frankly, if you’re worried about what’s in your food, you could do worse than focusing on what could really harm you: refined sugar. But that’s another story.
* Unless of course you don’t have any faith in our authorities competence or good intentions. In which case it’s a different issue all together.
