My experience is that almost all these cases are effectively "ChatGPT are fixing my attention problems" (not necessarily full ADHD, just people feeling it's easier with an impulsion no matter how random) For me, it's worth paying attention too, but more in the sense "what does it reveal in people ?"
Edit : also, one of his example :
"find my typos.” It finds a lot of the errors that are normally not caught by a regular spell checker: doubled-up words, punctuation marks, or words that are actual words but are misspellings for other words.
2005 spell checkers find all of these reasonably well.
(and, in fact, the only two reasonable examples he give is the innocence project - but it's an attention span thing - and the full text indexing one which is the exact use case LLMs were developped for and is inherently non generative)
There's one thing in Dune that I find Actually Revolutionary and that extremely few books series have succeded at It give the impression that tech actually advance. At a glacial pace, but also in ways that fundamentally change the settings.
Face dancers and synthetic spice are the two big one, in that they change the Dune world very significantly, and also relatively gradually. Compare and contrast with 40k, where they talk about new techs all the time but they never change the balance of power or really do anything, or Star Wars where it's unclear if any technologies actually get more advanced in the story.
