I want a personal LLM that learns what I find trivial or "known" and helps me find what's new. When reading Bitcoin news, I'm often just proof-reading what some journalist thinks he knows. An LLM could do that trivially, too but it could help me skip the stuff I know and summarize the stuff that's actual news for me.
On your podcast thing ... I want a generative LLM that turns a 2h podcast into a 5 minute podcast reproducing the spirit of the most relevant points, sounding as if that was all the podcast. ;)
