This is the same concern that has been raised about the personal devices (I think one was legit called “friend”?) that sits around your neck or something and just… records your day.
It’s super privacy invading since you are sending this data to a third party without someone else’s consent. (Which I mean we have normalized people consenting for someone else with Google so… yeah).
I think if we are talking about about fully local processing the conversation slightly changes. But there is still a major question about accuracy and the ability to have and say things at a meeting without worrying about it making it to someone else.
