Privacy is a double edged sword and apple has taken the other side of it compared to most other companies. Doing good ai while being privacy conscious is not easy, huge props to them and hope they succeed.
Is this fact or do we just think this because the only companies who have put resources into AI are companies that doesn't give a shit about your privacy (because they use it for their other products)?
It can be used for those things, or entirely different things that don't have anything to do with private data. It's not hard to not do these things just because it's possible to do them.
