How does this work in two-party consent states. IANAL but as I understand it, you need to permission to record someone in California.
As an aside, I don't consider myself a particularly paranoid person (relative to the median HN commenter, I'm probably still in the 95th percentile of paranoid-ness in the general population), but I couldn't imagine ever wearing a device that records my entire life and uploads it to Meta of all companies....
