Good engineering requires good reasoning skills and GPT has exactly zero reasoning. It cannot do the thing that humans do and it cannot do what a calculator can do. I think it is neat and fun, but that is all, a novelty.
I’ve used auto-routers for PCB layout and they will do a 90% job that takes just as much work to redo to get the last 10% as it would to have done it right by hand from the start. There may be a future for operator-in-the-loop type guided AI generative models but I don’t see a lot of effort devoted to making real systems like that. Watson seemed to have this potential and failed even after a brilliant display of ingenuity on Jeopardy. I see these models headed the same way.
