Maybe (I can't emphasize enough that I say this with a high degree of skepticism) they'll come up with a way of doing cited/credited/paid work where the LLM will include who "taught" it something.

Eg: instead of writing a blog post, you'll submit a knowledge article to an AI provider and that'll go into the AI's training set and it'll know "you" told it. And maybe (even more skeptical) pay you for it.

Again: highest degree of skepticism, but at the same time, that's the only way I could see people continuing to write content that teaches anything.
