Moral panic. We all have private tutors on every subject at our disposal now. It takes some special kind of mental gymnastics to conclude from this that no one will learn anything anymore henceforth. The article is just a long-winded way of saying "Kids today have it too easy", or, equivalently, "I'm getting old".
Yeah, I'm learning more than I have ever learned before. I suppose the worry is that people won't want to learn, though. That people will prompt the AI to just do things without caring about why and how they are done. That's a legitimate worry, but it's not new.
Having all the world's knowledge at our fingertips didn't seem to make us any smarter (quite the contrary, from where I'm sitting), so I'm skeptical that having private tutors at our disposal is going to. Perhaps for the ever-curious few, but for most people those "tutors" will probably just end up as another form of entertainment.
