I'm with you on the YouTube side - I stopped making my own videos earlier this year when I burnt out, and now I'm finding myself increasingly irritated just by the thumbnails when I visit the site. I'm definitely viewing less than I did last year.

I hadn't considered the impact on manga. Machine translations are probably helping with fan translations for more niche projects. I haven't seen any obvious AI art myself yet but I do tend to read stuff from smaller creators on slower release cycles.
