Earlier quoted context omitted.
LLMs are already better than books for exploring some ideas. But in conversation form. Until we get better versions of o1 that can generate insights over days and then communicate them in book form the loss of interactivity and personalisation makes LLM books pointless.
An interactive conversation / tutorial session beats a book pretty much all of the time. Nonfiction books contain a lot of information that's redundant to a reader familiar with the topic, and not enough for someone new. They don't backtrack if you clearly missed an important point. And so on. It's like fractal geometry.
I do suspect that interactive media is just strictly better in theory. But maybe there will be a period of time where bespoke AI-generated books make sense.
