If I'm being honest, a lot of my professors (perhaps a big majority even) were just bad teachers and I got much more value out of the textbook, looking up stuff on the internet, or just tinkering with the at home assignments. I can say with 100% certainty that ChatGPT would have been infinitely more helpful in me learning calculus compared to the professor who taught my class in university.
I also don't really align with the issues he has with students asking for the slide decks used in class. If it can help your students learn the material, the whole purpose of the class, then what's the big deal? This point in particular almost made it seem like he's a bit salty over his students not being deferential enough to him.
All in all, despite doing many of the things that this writer takes issue with when I was in college myself years ago, I have a great career and I'm good at my work. So I think the kids are going to be just fine.
