I would argue that people you are describing enjoying Tik Tok and being too lazy to look stuff up themselves, are not really engineers. You could also frame it as, information technology got so mainstream, even people with no technical background whatsoever are part of it. Engineers and tech nerds still exist, but they are a minority now.

I always thought cigarettes contain tar, as in the substance asphalt on the road is made from. It always felt weird to me, why would they put it in the cigarettes but I figured maybe they need it so the tobacco doesn’t fall out or something.
