The number one issue that humanity faces today is technological growth. If you look under the surface of most political issues, what drives them is the way technology has given us abilities we did not previously have, or information we could not previously have accessed.

What makes this especially powerful is that technology evolves much faster than human beings do. Technology can go through many generations in the course of one human’s lifetime.

This is important, because in evolutionary biology, new traits usually emerge over the course of generations. (This is why biologists usually study traits in organisms with short generations. You can observe multiple generations of flies over the course of a year.)

But since technology moves faster than humans can evolve new traits, it means that we are always playing from behind. When I was born, cell phones were huge, unwieldy things used by rich people, sales reps, and techies. Now they’re everywhere, and are more powerful than the top-of-the-line supercomputers of three decades ago.

For the last 200 years, technological progress has been increasing at an incredible rate. And humans have often suffered by being slow to adapt. This is illustrated most dramatically by wars: in World War I, the officers had all been trained in tactics derived from the Napoleonic era. This resulted in huge massacres, as cavalry and infantry charges–which would have worked against men with inaccurate single-shot rifles–were torn to pieces by machine guns. Technology had made a huge leap in the century between the battle of Waterloo and the battle of Artois. And that was as nothing compared to the leap it would make in the next thirty years, with the advent of the Atomic Bomb.

The thing is, while it may seem to us like a long time since the days of cavalry charges and flintlock rifles, in terms of human history, that’s a drop in the bucket. Homo sapiens first emerged roughly 200,000 years ago. On that scale, Waterloo might as well be yesterday, and the Roman Empire was just last week.

For the vast majority of our existence, life was pretty much the same: people worked the land and hunted and raised families. Periodically, they organized into larger tribes to make war or trade. If you took a citizen of Athens from, say, 450 BCE and transported him to Renaissance Italy—nearly 2000 years later–he’d still have a pretty good handle on how things worked once he got past the language barrier. Whereas if you transported somebody from 1890s London to the present day—a mere 128 years!—he’d have no idea what was happening.

When you read history, it’s easy to be struck by how human nature seems unchanged over the centuries. We can recognize things in the texts of the earliest historians and philosophers that seem analogous to modern phenomena. While it may seem like this means human nature is eternal, what it really signifies is that it hasn’t been that long, in biological terms, since what we think of as “ancient times”.

It’s commonplace to observe the technology changes, but human nature remains the same. But observing it is one thing; grasping the full implications is another.

For instance, there is a major “culture war” debate in the U.S. over the issue of transgender rights. Those who favor transgender rights view their opponents as closed-minded bigots. Those opposed see the others as radicals bent on destroying the social order. What both sides ignore is the fact that until very recently, transgender people had no medical treatment available to them. For hundreds of thousands of years, transgender people had no option but to live in the body they were born with. And the rest of the population scarcely even knew they existed; and so built whole societies premised on two rigid gender roles. It wasn’t until very recent breakthroughs in medical technology that any other option became viable.

Once you view it in these terms, you realize it isn’t a liberal plot to destabilize society, but simply a group of people able to access treatment that previously did not exist. Likewise, you also realize the reason so many people are responding with fear and suspicion is that history and tradition provide no guidelines for how to deal with the issue. It simply wasn’t possible in the past.

A number of social conflicts, I suspect, are in fact the result of people being optimized for a very different world than the one we actually live in. Ancient prohibitions against homosexuality, sodomy, and other non-reproductive sexual behavior made some sense in the context of their time—in the past, when mortality rates were high, people needed everyone who was physically capable of reproducing to do so, personal feelings notwithstanding. It was about survival of the group, not any one individual.

Nowadays humanity is threatened more by overpopulation than by extinction—but we’re still adapted to the world of thousands of years ago. That’s just one example. I think people in the developed world still have a slightly-irrational fear of famine; simply because we evolved over millennia where food was, in fact, extremely scarce. (This is why philosophies like the so-called “abundance mentality” seem so counter-intuitive. In the past, it would’ve been suicide to assume there were enough resources for everybody.)

Instinct is a powerful thing, and incredibly dangerous when it gets outdated. To borrow an example from Paul Graham: because human beings haven’t had the power of flight until recently, it’s easy for our senses to be fooled in bad visibility.

Of course, this is something where we use technology to make up for our own shortcomings. A human being would have no idea how to fly a plane if not for instruments that correctly show the position of the aircraft. And this leads to another obvious point about technological evolution—it is, in many ways, nothing short of miraculous for humans. It allows us to accomplish things our ancestors could never have imagined. Whatever bad side effects it has, no one could ever rationally argue that we’d be better off getting rid of all of it and returning to primitive life.

The saving grace is that technology has been designed by humans and for humans, and so generally is compatible with the needs of humans. The things that conflict with human needs aren’t usually a direct result of this, but rather side-effects the designers never thought of.

But side-effects, almost by definition, are insidious. Any obvious, seriously harmful side-effect gets fixed early on. The ones that don’t usually fall into one or more of the following categories:

• Not obvious
• Don’t seem harmful at first
• Can’t be fixed without destroying the benefit

The designers of automobiles probably never thought the exhaust would cause pollution; even if they had, they probably wouldn’t have realized that cars would be widely used enough for it to matter. Marie and Pierre Curie had no idea the new element they had discovered was dangerous. It seemed like just a useful illuminative substance. And pretty much every communications technology in history, from the printing press on, has the potential to spread pernicious lies and propaganda just as much as news and useful information. But no one can figure out a way to remove the bad information without also getting rid of the good—the only option is censorship, which can pose a danger in its own right.

I’ll say it again for emphasis: technology is evolving faster than humans. As a result, our instincts will often lie to us when it comes to dealing with technology. It’s the same way modern junk food is engineered to please our taste buds while poisoning our bodies—it’s designed to set off all the right sensors that tell us “get more of this”.

The rise of nationalism throughout the world in the last decade has gone hand-in-hand with the rise of social media. It’s not a coincidence. Social media plays to an old instinct that takes human society back to its most basic state: the tribe, and the desire to win approval from that tribe. But in the past, when we were in tribes, we didn’t know what the rival tribes or nation-states were doing—they were in far-off lands and rarely encountered each other. But now, we always know what they are doing—they are just a click away. And because they are a different tribe, our instincts tell us to fear them, as our ancestors feared invaders from distant places.

What can we do about this? We can’t get rid of technology; nor would we want to. And I don’t think it’s a good idea to make it into a political question. Politicians want easy, non-nuanced issues, where they can cast themselves as leaders of a huge, virtuous majority against a tiny, vaguely-defined band of evildoers. That would be a terrible thing to happen on this issue. As we’ve already seen in the social issues I’ve mentioned earlier, politicians tend to cast these things as moral questions rather than technological change ones.

We’re going to have to deal with this one on our own. But how? After all, technology brings huge benefits. How can we keep getting those while minimizing the side effects? We don’t want to completely ignore our instincts—not all of them are outdated, after all—but we can’t always trust them, either.

The best advice I can give is to always be on the lookout for what side-effects technology produces in your own life. Always ask yourself what it’s causing you to do differently, and why. Then you’ll start to look for the same in the wider world. We know human nature doesn’t change that much; so when you see or read about a large number of people behaving in an unusual way, or a new cultural phenomenon, there’s a decent chance that it’s in response to some new technology.

It’s easy to look at the dangers of technology and decide you want to opt out, throw it all away, and return to the simple life. This is probably healthy in small doses but it’s impractical on a large scale or for an entire lifetime. What I’m advising is cultivating an attitude of extreme adaptability, where you are so flexible that you can both use new technology and see the potential problems with it coming before they hit you. Listen to your instincts, but know when you need to disregard them. Remember, your instincts are optimized to give you the best chance at survival in a world of agrarian societies and/or tribes of hunter-gatherers. And they are damn good at it; but their mileage may vary in a world of computers, nanomachines, and space travel.
