I'd argue that negative people where correct. People can't spell anymore, not even with a spellchecker. Maybe they never could? I'm not against spellcheckers, I think they are amazing, but they haven't helped much.

WordStar is not the problem, StarWars is. Popular culture has become so vapid that when it comes to writing and the thinking behind writing, most people fare worse than an LLM. I know that old people have been saying this basically since ancient Greece, but it bears repeating: the youth is lost.
