> But many people want the world to be simple
This is the source of so much insanity in the world, not just with regard to allocating labor. Details matter, but people who plan "timelines" desperately don't want to hear it. They can go through whole careers without being forced out of the cozy illusion that the world is simple. It's hard to get a man to believe something when his salary depends on it not being true, the market can stay irrational longer than you can stay solvent, etc.
