Lately I’ve been practicing a new form of exercise to me (mace and heavy club swinging, if you must know). While most of my learning has come from online videos, I’ve also bought a few self-published books by people who made the videos. The books are helpful, too, but they are not written well at all—not surprisingly, since the authors are professional fitness trainers, not writers. A year ago, I would have wished that they had hired a good editor to clean up and tighten their prose. Now I would just recommend that they run it through GPT-4. That would make their books much more pleasant to read and learn from, and it would cost them a lot less money.
