Well, I think there's a difference between something being answerable by ChatGPT, and someone being able to take that answer, understand it, and use it to deliver value.

Moreover, while ChatGPT is really good, it can make mistakes, and if said mistake isn't an obvious one, then you'd need to have a good general understanding of the thing you're asking a question about to spot that mistake.

We should also consider that ChatGPT won't be free forever, so it might be a bad idea to change teaching in a way that assumes that these kinds of things will always be accessible to students and wherever you're going to work.
