I think humanity has a golden age coming. Unfortunately, a.) as John Maynard Keynes pointed out, “In the long run, we are all dead.” Accordingly, I don’t expect I’ll live to see that great age. And, b.) said great age is likely to come on the backend of a tragic period whose reach and devastation will make the Second World War seem like a puny and short-lived regional skirmish by comparison. [I also think there’s a good chance I’ll miss the worst of this, but there’s no accounting for the rapidity at which it might move (and the process has begun.)]
The root of this combination of relative near-term pessimism and long-run optimism is the observation that we are experiencing a technological revolution that there is no reason to believe won’t end in machines that are both smarter and more capable than we, and we have no plan for what to do in that scenario. We have no conception of what an economy looks like in which machines do everything faster, more cheaply, and more efficiently than human labor. I wouldn’t be so pessimistic if our institutions and legal frameworks were trending better and better, but — in fact — after years of spreading rule of law and democracy, we are starting to see global shrinkage and a rise of a strange populist authoritarianism that I can only imagine being catastrophic under the stress test that is to come.
Why the long-term optimism? Nothing lasts forever, and tough times breed tough and capable people. [Whereas comfort addiction is a major factor in our near-term predicament.] I think the Golden Age will be humans learning not to be defined by production / consumption but by developing the human body and mind to its utmost capacity.
A lot of people are worried about population collapse. I am not so worried about that. I think that: a.) humanity could use some thinning; b.) we do fine with long time scale threats. As pressures rise, the adjustments start and — perhaps with some growing pains — we’ll get where we need to be. The AI / Machine Learning revolution concerns me because I suspect it will happen too quickly to steer the ship (like being in an aircraft carrier as a tsunami comes, there’s no agility to navigate out of the way and no speed to outrun it, you just have to take the damage and try to recover.)
You were probably looking for an answer like flying cars, but I gave up on those long ago.
