I dream about an AI service that can curate me a newsletter given some sources (RSS, Twitter feeds, youtube feeds, whatnot) and send it to me regularly on a given interval. It would avoid duplicates and essentially identical stuff [1], weigh and choose the most interesting ones, and present them to me in a nice, readable format. Ironically I would not use such service if it existed because it would be very anti-privacy.

[1] Twitter is weird. I only follow ~15 accounts for events and (want to) use twitter only for that, but the way people usually post updates about events is to repeatedly post what is essentially the same tweet, and even with that many accounts followed it becomes a mess. I end up never checking it because it's basically a puzzle.
