I'm freaking out. I just created a GPT to help me answer Lisp questions. I uploaded 10 of the best Lisp books (including Graham, Norvig, Siebel, and Touretzky) and it's giving me great answers. This is even better than the Hyperspec. What an amazing tool. It took me less than half an hour. I'm blown away.
