For example, I think the goal is to merge all entry fields into a local one that manages and monitors output. I should be able to see and record a stream of everything I do online but I can't. That stream, being a representation of me, is what's valuable. Straits of Hormuz on a person-by-person basis.
How many entry fields are there that you use? email, video, social, crypto, HN, chat, apps... the list goes on. There's a lot of duplicated effort there. Why so many?
