Like any tool, it depends how you use it. I have been learning a lot of math recently and have been chatting with AI to increase my understanding of the concepts. There are times when the textbook shows some steps that I don't understand why they're happening and I've questioned AI about it. Sometimes it takes a few tries of asking until you figure out the right question to ask to get the right answer you need, but that process of thinking helps you along the way anyways by crystallizing in your brain what exactly it is that you don't understand.
I have found it to be a very helpful tool in my educational path. However I am learning things because I want to understand them, not because I have to pass a test and that determination in me to want to understand is a big difference. Just getting hints to help you solve the problem might not really help in the long run, but it you're actually curious about what you're learning and focus on getting a deeper understanding of why and how something works rather than just getting the right answer, it can be a very useful tool.
Trump: makes incorrect claim
Moderator: Actually there is no evidence that happened
Trump: well I saw it on TV! Someone said it on TV! Someone wouldn't just go and say something on TV if it wasn't true!
Shouldn't the president of the country have a bit of higher standard of evidence than "I saw someone say it on TV"?
