I don't think it's fair to blame this on LLMs. The last time I bought or even looked at a book of this type was easily 20 years ago.

And I wouldn't have it any other way. I remember my ginormous Visual Basic 3 Bible from the 90s with great fondness and nostalgia, but thumbing through a dead-tree book to figure out computery things is just not a thing I care to do.

Having said that, I still think there's room for computer related "books"... of the digital kind, at least. It honestly feels a little absurd to even consider buying a physical book for this sort of purpose.
