I was thinking about this a few years back, when I was working on firmware for pre-smart-phones. Probably something to do with getting old and forgetful :) The trouble with audio - as everyone has pointed out - is the privacy and storage issues. What I would be interested in is some way of producing a condensed "markup" of your day, easily searchable using a voice assistant. It would record the basic facts but not the verbatim conversations. When I first thought of this in any depth it was still unfeasible, but now I think much of it is already there. Still, a big project. Maybe smaller, niche versions for particular tasks would have to come first?
