One thing that LLMs will give us, is the ability to make really interesting and exciting tutorials. We can do that by hand, now, but it's a lot of work. I know of which I speak. I've been doing tutorials forever, but they haven't been particularly popular. Part of that, is that I'm pretty bad at self-promotion, and having that eau d'expert scent about you, is a big selling point. I really don't waste much time, trying to convince people that I have something they want, so they don't want it.

That part will still be necessary. I suspect LLMs can help polish and optimize self-promotion, but that also means everyone else will be doing it, and the competition is likely to be stiff.
