At this point, I think phones can be compared to a home in terms of privacy.

In your house, you might have private documents, do some things you don't want other people to have or see just like what we have on our phones nowadays.

The analogy I'm trying to make is that if suddenly the government decided to install cameras in every houses with the premise to make sure no pedophile is abusing a child and that the cameras never send data unless the AI done locally detects it is something that I believe would shock everyone.
