I thought this was fairly obvious. I don't consider any of the AI models I've worked with particularly smart, but they've read orders of magnitude more than I ever could in my entire lifetime. They have far better book knowledge than I have, so that's how I use them. I use them for things that I suspect other people out there would know, but I don't. But when I work on something that I suspect is truly new, the models rarely understand what I'm doing, and I've got to do it myself. Although I still poll them for basic principles, best practices, and other advice.
