> Yup it's wild to me how much anxiety there is about cameras while no mind is given to microphones. Conversations are much more privileged than potentially seeing me in my underwear.

It depends on the person, I don't think you could gain much from me? I don't say credit card numbers out loud, I don't talk about hypothetical crimes out loud. I don't say my wallet seed phrases out loud. I also don't type in my passwords. Yes you could probably find out what restaurant I'm ordering delivery for, but other than that I suppose my conversations are really boring.

The cost of feeding your entire years speech to an LLM will be $0.5/person. I'm sure summarized and searchable your conversation will be very very valuable.
