How is it not a dealbreaker that companies like Google and Facebook are destroying internet privacy and undermine the whole foundations of democracy. If I visit a friend I would require him to tell me if my speech is being recorded by google or anyone else that he is aware of, privacy is a matter of dignity and will always be the cornerstone of human rights, it's not a matter of personal choices/concerns it's a fundamental concern of how we want our society to be.
It's not like these devices are open microphones pushing data to Amazon/Google/Microsoft. They use onboard processing to detect their personal wake words and then stream your audio until a defined audio gap. That is then processed into text and kicks off the automated routines. Do they analyze this for ad-related keywords? Perhaps (Probably), but that is a different argument that is valid vs. an invalid argument that it's always streaming.
And where's the guarantee of that? Can we see the code? Can we turn off the microphones in hardware?
All it takes is for Apple/Microsoft/Google/Amazon to push a system update, and, voila~~~
Skynet listens to all.
