Like any other tool, it's more a question of how they're used. For example, I've seen incredible results for students who use ChatGPT to interrogate ideas as they synthesize them. So, for example, "I'm reading this passage PASSAGE and I'm confused about phrase X. The core idea seems similar to Y, which I am familiar with. if I had to explain X, I'd put it like this ATTEMPT Can you help me understand what I'm missing?"
The results are very impressive. I'd encourage you to try it out if you haven't.
I try to use AI to automate things I already know and force myself to learn things I don't know.
It takes discipline/curiosity but it can be a net positive.
They should just simply try it. Start with something you actually know to see how useful it might be to you with your prompts.
