There is so much wrong with this...

AI is a range of technologies. So yes, you can make surveillance with it, just like you can with a computer program like a virus. But obviously not all computer programs are viruses nor exist for surveillance. What a weird generalization. AI is used extensively in medical research, so your life might literally be saved by it one day.

You're most likely talking about "Chat Control", which is a controversial EU proposal to scan either on people's devices or from provider's ends for dangerous and illegal content like CSAM. This is obviously a dystopian way to achieve that as it sacrifices literally everyone's privacy to do it, and there is plenty to be said about that without randomly dragging AI into that. You can do this scanning without AI as well, and it doesn't change anything about how dystopian it would be.

You should be using end to end regardless, and a VPN is a good investment for making your traffic harder to discern, but if Chat Control is passed to operate on the device level you are kind of boned without circumventing this software, which would potentially be outlawed or made very difficult. It's clear on it's own that Chat Control is a bad thing, you don't need some kind of conspiracy theory about 'the true purpose of AI' to see that.
