Now music recommendations? That might just work given that algorithms are already doing a decent job at presenting new ( to the particular user, not by actual age) music that the user may enjoy
In my experience they really suck..."oh, you liked that song from this artist? let me just push a shitload that is categorised in the same basic genre without actually considered the specific track you liked"
It's so ridiculously generic in its suggestions it's useless. So yeah, AI can almost only do a better job at this than currently.
I haven't bought from temu, but I've bought loads of stuff for various things on similar sites like aliexpress. If I have the time to wait for the shipping, it's the exact same components as I buy in electronics supply stores here, but at a fraction of the price. I prefer to not pay a 300-400% markup for no real reason.
