A few weeks ago, I postulated several conjectures, and my PhD student thought about them and came up with proofs or counterexamples for each of them. I was overjoyed and excited for our future work together.
I imagine a scenario where instead I had asked a chatbot to prove the theorems for me. Even if it did prove the theorems (extreme doubt), I think getting such a proof wouldn't have made me feel anything. No one's achieved anything.
