IIRC Nietzsche's writing style changed because of the advent of typewriters. He didn't need his pen and so wrote more freely (at the apeed of thought).

I think the general concepts are cognitive offloading and second order consequences; changes in human behavior due to the technology. Or just: use it or lose it.

And maybe Jevons Paradox is relevant? E.g., when compact fluorescent light bulbs were introduced people got cheaper lights so people installed more sich that a net energy consumption was increased per person. But then applied to LLMs: generating text/information becomes increasingly easier and instead of less text we produce more and thus more llms are used to consume that information overload to summarize, making us spend more time on text.
