I've experimented with things like this, e.g., the Narrative Clip. I think the concept is quite novel and interesting, but the privacy implications are just far too gross for anything outside of an experiment. Of all companies, I find it appalling that it's Apple implementing this one.

I don't even know how this is supposed to work e.g., in states with call recording legislation, let alone any new legislation. It feels utterly appalling that every Apple watch could theoretically be recording all surroundings now.
