How to convince interns to not use ChatGPT blindly?

I have a couple of interns under my wing in my own consulting startup. How do I convince them not to use ChatGPT blindly and actually go into ReactJS or Java documentation or Google issues? How do I convince them that they need to make a Proof of Concept to understand a complex issue?

This is so difficult. They keep spending more and more time on a specific task where GPT gets stuck.

I have talked to them and they have good problem solving skills as I regularly see, but when they are working on an item (feature or a bug), they just won't read documentation, or look at solutions on StackOverflow, or make a quick PoC to establish what is going wrong. They will just keep digging into GPT for 'quick' solution.

I don't want to fire them in a couple of months and bring more interns because new interns are going to do the same. ChatGPT is an excellent tool but it feels like we are going to see a very clear difference in good developers very soon! This isn't a rant and I want to find a genuine solution to this problem.
