@darius "With innovation there isn’t a last nugget" - I'd never heard this (early) Bezos quote before and it's an interesting idea to examine in light of the past 20 years. It seems generally true that for any given thing humans do, we can come up with an at least slightly better / cleverer way to do it, or at least understand the doing of it. But this hasn't created a "long boom" by any definition, it's produced a couple booms (mobile computing) and a series of crises.
