I think the future has to be feed ingestion that is 100% controlled by the user. To some extent we were there with RSS readers. I'm still able to retrieve Twitter feeds with an RSS reader. Everything comes together in one place, in order.
If this is done on device and everything is archived, it starts getting really powerful. For example, after the 737 MAX door incident, I searched "Boeing" in my RSS reader and instantly had a list of news stories going back over the past year. (The number of 737 incidents that has been happening around the world is a lot more than what sits in the top of the news, but that's another discussion.) A local LLM could even summarize large amounts of stored headlines and tweets going back over years, and that's tech that works today.
I don't want third party ad platforms (which now consists of Google, Facebook, Apple, Microsoft, Amazon, and more) measuring, running tests, re-ordering, and deleting on my communications. The LLMs and machine learning advancements are going to just make this more invasive, ugly, and manipulative.
Sure, hn is largely about VC backed startups going on to try to have a multi-billion dollar IPO. It's also about disrupting incumbents. I can't think of a better path to disruption than coming up with business models that choke off their user-bases and end ad monetized surveillance. I for one have no interest in a future where I wear an Apple/Facebook/Google controlled AR/VR headset that has cameras to make sure my eyes are looking at all of the ads which are targeted based on the other pixels it knows I looked at. (I feel like a paranoid schizophrenic writing that, but that is what they are making.)
