Is it possible that we’re about to turn a technological corner and it’ll be like the rise of the web - a revolutionary new media platform - all over again? Sure. Maybe I’m wrong. But I’m pretty informed, and I don’t see a web-like technology where everything is done and working, and just needs to be explored. There’s no green-field tech on the horizon where simple refinement is going to open up new industries. We’re back to waiting.
Today we’re increasingly focused on stuff that might not even work at all (e.g. fusion), or that has huge technological or societal barriers that are unsolved (e.g. robots, electric cars) It’s a different world, and even if something revolutionary comes around the corner next week, right now the playing field is fairly competitive.
