I think one of the issues which needs to be solved with AI assistants is its not just a dumb speaker; but some of the requests, it doesn't just phone home for the servers to respond to the question, rather if its a typical everyday command its stored locally in the machine.
That way its not constantly sending stuff to external servers..
I'm somewhere in between with this and quite unsure what to believe. It definitely makes sense that it's not sending all the information back for analysis as it only reacts only to certain phrases, but then again, if we believe so strongly that someone is in fact, spying on us through our laptop web cameras then home assistant AI would be just as useful if not more useful for gaining various information, no?
