So a serious AI product would have to have my data (contexts, conversations) in a "secure enclave". If backed up, it needs to be encrypted.
I want a context and history that, over time, essentially knows everything about me.
It's one of the things that has been rather fascinating about Claude & Co.— he'll come back with things like, "Since you are already familiar with the ESP32…" or, "You already have a heat press from your work with dye sublimation, that will work nicely to set the inks when you screen print t-shirts…"
(Shades of "Diamond Age"… I imagine it helping me recall things when I am in my old age, notice patterns in my life I might want to break free from, etc.)
