Googling stuff online doesn’t make you a programmer either. You still have to learn it, know how to apply what you look up, understand how the computer works. Although it’s easier to learn by yourself, at least partially because there are no lives at stake.
And doctors look up plenty of stuff too. Only a fool would think they already know everything.
I switched newspapers when I noticed that every time my newspaper write about something I actually knew about, they wrote garbage.
Sapiens does present some really powerful ideas, though. I enjoyed it a lot, but the book clearly glosses over a lot of details. Then again, it tries to tackle a ridiculously big scope, so I can see how it can’t get into all of the details. I still consider it a worthy read despite its shortcomings. But read it more for the ideas than for the facts.
