My answer is it is bitcoin. Bitcoiners are idiots, by and large (just look at Stacker News comments), and it is the dynamic process of free markets that actually fixes things. Give me the world after 100 million bitcoin of cumulative GDP post-hyperbitcoinization, that's when things will really ramp up.
Anyway, this is my roundabout way of also saying it will take too long, so I can't wait for bitcoin to fix things: just have to charge forward through the fiat mud and fix things myself.
One thing I want to fix is the composition of lipids in the world, which no one else is addressing seriously in a globally scalable way, which requires considering cost -- sincere bitcoiners understand that cost is a key part of value and scale. Anyway, take a look at this twitter poll if you want to improve the odds your children live in a world with less poison.
