Let’s say you’re a student and you use ChatGPT to write your essays for you. Give it the right prompts and it will produce pieces that are good enough to get the grade you need. That seems like a win: it saves you time and effort, presuming your tutors don’t notice or don’t care. Maybe you get through the whole of university this way. But be wary of this equilibrium. Over the longer term, you will be stunting the growth of your own mind. The struggle of turning inchoate thought into readable sentences and paragraphs is a powerful exercise for the brain. It’s how you get better at thinking. It is thinking.
