Wait, this just looks like cryptographically signing pictures. What's so scary about that? You can do it today from your terminal if you feel like it.

I guess I agree that the 'trusted computing' stuff it seems like they're trying to do is a little scary, but the tech isn't really there yet, at least not on the desktop (look at the fiasco that is Intel SGX) and it's happening with or without whatever this CAI thing is.

I guess a world where your iPhone's camera sends signed frames to the processor's secure enclave which processes them and signs them with a key signed by Apple is... a little different from today? They do basically this for Face ID today.
