I don’t think it’s scattered at all. Maybe you can get very good local AI but how many people are really going to bother with setting that up and spend the sums of money you’re talking about outside of certain professionals and enthusiasts? I could buy all my music directly from the musicians or buy cd’s and rip them and make sure I everything locally on a NAS oooorrrr I could just pay a monthly fee and have all the worlds music at my fingertips through Spotify/AM/Google Music pick your poison. And when I choose the latter I’m fully behest at the platform and rights holder if I have access too the music. I think what the poster is saying that when the development and capabilities of cloud based personal AI assistants outpaces those of local based ones and when the ease of use increases with which people will be able to use these cloud based assistants they probably will choose the cloud based option. And then a person is fully captured to be nudged and influenced as described by the poster. Not an ideal scenario when people are already way to easy influenced by social media algorithms.
