I don't have any deep insight into ChatGPT. I used to work at an AI (i.e Machine Learning) company, but not on the math side.
What I learned is that all ML is derivative. It only knows what you teach it, and nothing else. So the ChatGPT and Midjourney products aren't that interesting to me. They are obvious simulacra.
I know the tech is garbage since my gauge, a former co-worker, is gushing about ChatGPT on LI. He is wrong about everything, with the prognostication powers of a dead fish.
