Hasn't thinking already become a hobby for most people, and most delegate their thinking to others?

Think: those in authority figures, for church or politics. Or science or chemistry. And especially in their own health, which should always remain part art. A few nerds on the internet, like us in hacker news, are still remaining open to question and apply our hard thinking to tough problems. But most people: they've resigned and bought the belief they are not qualified to think about hard problems.

This sounded really like elitist thinking. I don't know what most of the people do but I know my wife is a caveman of we are speaking about technology but if we start taking about law then suddenly I'm half brained chimpanzee with banana in the nose trying figure out why I can't drink it

Even my uncle who work as a carperter proved to me to know more about math and physics than I would ever thought physical labourer would know.

Probably. If the remaining who think go too, we're done for.
