Consider this in addition. How many are beating their heads off a wall, and then solve it. Perhaps they are happy they figured it out. But then they remember this is for a piece of garbage ad-tech app, or part of a google project that'll go in the garbage in 2 years, or something to steal even more private information from end users, or it's another CRUD web app...

All the while they're being sold on how they're "changing the world..." or "innovating."
