Universities and teachers will need to adjust to the reality that this stuff is here to stay. There's some value in learning how to write properly, of course. But there are other ways of doing that. And some of those ways actually involve using LLMs to criticize and correct people's work instead of having poor teachers do that.
I did some teaching while I was doing a post doc twenty years ago. Reviewing poorly written student reports isn't exactly fun and I did a fair bit of that. But it strikes me how I could use LLMs to do the reviewing for me these days. And how I could force my students to up their standards of writing.
These were computer science students. Most of them were barely able to write a coherent sentence. The bar for acceptable was depressingly low. Failing 90% of the class was not a popular option with either students or staff. And it's actually hard work reviewing poorly written garbage. And having supported a few students with their master thesis work, many of them don't really progress much during their studies.
If I were to teach that class now, I would encourage students to use all the tools available to them. Especially AI. I'd set the bar pretty high.
