I feel like this is missing the point of GenAI. I read fewer books than I did a year ago, primarily because Claude will provide dynamic content that is exactly tailored for me. I don't read many instructional books any more, because I can tell Claude what I already know about a topic and what I'd like to know and it'll create a personalised learning plan. If I don't understand something, it can re-phrase things or find different metaphors until I do. I don't read self-help books written for a general audience, because I can get personalised advice based on my specific circumstances and preferences.

The idea of a "book" is really just an artifact of a particular means of production and distribution. LLM-generated text is a categorically different thing from a book, in the same way as a bardic poem or hypertext.
