I think the next phase of LLM products is LLM + RAG but the retrieval system is personalized per user and behaves differently based on user preferences, social graph, etc. What are products doing this?

Permissionless protocols like farcaster and bountycaster get really interesting in this context too.

I've thought about this a good bit. There're a few useful systems that could spawn out of this in agent-land. 

I've wanted to build an agent that has a U(ser)RAG and K(nowledge)RAG that it pulls from in a dynamic way to basically build some long-term and useful personal assistants on top of tools like AutoGPT
