The recent wave of terrorist attacks has made me worry if technology will ever, or during this century, advance to the point where regular terrorists are able to destroy the world. Humanity has, so far, survived 71 years when it was possible to blow up the world if you had the resources of a superpower. But what if technology advances further to the point where destroying the world gets within the means of your average, run-of-the-mill doomsday cult? Or even a deranged individual like Ted Kaczynski?
Related to this, I think if we would really live in a world like that of James Bond movies or superhero comics, with supervillains regularly trying to destroy the world, the world wouldn’t survive for long: in order for the world to survive, the James Bonds/superheroes would have to win every single time, while in order for the world to be destroyed, the villains would only have to win once. And eventually that one time would come- if you keep rolling the dice, sooner or later they will come up six.
Man, with Britain voting to screw itself, Turkey going full dictatorship, and Trump promoting fascism here, to say nothing of humans slowly roasting the ecosphere, you don’t have enough to worry about?
For what it’s worth, if the world gets blown up, it’s still more likely to be a superpower that does it. Or at least a medium-sized state. This isn’t meant as a reassurance; it’s a reminder that we’ve escaped from nuclear holocaust by the skin of our teeth several times. Here’s a Mefi page on near misses.
For non-state actors, a weak consolation is that though they are careless about human life, they are rarely self-genocidal. That is, there’s a rough rationality to extremism: atrocities are cheap and get attention, but the extremists do not actually want their enemies to destroy them all, because of course then their cause is dead. Of course, like any other politicians, extremists can misjudge likely results. Osama bin Laden probably didn’t plan on getting killed in a raid.
It’s always worthwhile to get some historical perspective. Here’s a chart of terrorist deaths over 40 years:
That is, outside of three countries (two of which are basically in civil war), terrorism is down worldwide. (Also, for comparison, the annual number of road traffic deaths is 1.25 million.) Nothing to be complacent about, but we can too easily get the impression from the news that everything is terrible and always getting worse.
If you’re thinking of futuristic threats, it’s also worth remembering that people will have a strong motivation to develop futuristic counters. It’s not great worldbuilding (or prediction) to suppose that some agents get doomsday-in-a-box weapons and the motivation to use them, while their enemies have no clue about this, no similar weapons, and no conceivable responses.
Not that doom is impossible! But terrorists generally have their own enemies, they don’t want to destroy the world, and their abilities are limited. But feel free to be terrified of Trump with the nuclear football.
