Same thing that happened to intellectualism. One there's significant pressure against it by growing monetization of anything and everything, the whole monopolization of education, then there's steps against having an educated and therefore 'dangerous' populace particularly in regards to literacy. There's no major financial incentive for your average person to be an intellectual or self-taught in any skill, there's also no social gain. Its not useful/cool to be smart on your own. People that know more things things can figure out are being exploited faster than those who don't (anyone with a brain eventually will, but they won't find a framework to put it to and instead blame the lizard people on Mars south pole), and if they read reasonbly, well about x1000 times more risk.

Arguably, with the pandemic and supply issues there is a growing incentive in say, knowing EE 101 to unbrick a ROM, knowing how to plant an efficient veg garden, or basic car repair for the more practical things that are on the border between working knowledge and education. I think the pride will eventually return, since I don't see things improving any time soon.
