So, probably AI had a significant impact here, but I noticed this myself, a non-AI using person, where I bought fewer books than before. There are many reasons for this, financial ones but also practical ones (don't have to story physical books). As well as lack of time; I need to manage my time better, so I have to skip on reading too many new books until I have finished reading the existing stack. Plus the www also has a lot of information. AI may have been killing more humans here (it is skynet after all), but the underlying problems started being serious way before AI already, in my opinion. Also google search being ruined by Google; it is so useless nowadays.
