That wasn't my experience in school, but there's a good chance you were just in an introductory class or similar. However, that doesn't change anything about my argument. If you need the log of something, you knew that you needed to look up the log in a table to solve the problem. ChatGPT removes the need to even understand that you can use a log to solve a problem, and instead spits out an answer. Yes, people can use ChatGPT to accelerate learning, as one would a calculator, and in those instances I think it's somewhat valuable if you completely ignore the fact that it will lie to your face and claim to be telling you the truth. However, anecdotally I know quite a few folks that are using it as a replacement for learning/thinking, which is the danger people are talking about.
