I believe growth is exponential. The growth of complexity. The author mentions how it can get you 70% of the way there, well Pareto is a bitch. Once the details matter more the difficulty grows evidentially (well power series). What people fail to realize is despite what we've done is incredibly and no easy task, it's "the easy part". And progress is unfortunately constantly like this. Because as we progress we are effectively solving higher order solutions. Solve your Taylor series problems. If you've done up to 4th order and still need 5th, everything previously is (usually) "easy" in comparison. Getting to the 6th is no different, and so on. And of course it gets harder, we made progress! The naive part is to think the future will be as easy as the past looks in retrospect, not as hard as the current state looked a priori.
