I'm wondering why the article fails to mention that there is a sufficiently good and easy mechanism to compare and verify the new safety numbers. You just talk to your peer and read the numbers - and the peer can verify them.

This will fail when AI software gets really good at imitating voice in real-time during casual talk, but we're not there yet (or - if that is my threat model, I'll find an out of band way to verify)

A sufficiently good mechanism from a cryptographic standpoint, but which from a usability perspective totally falls down because people never do it.

It’s a very worthy goal to make these events rare and scary so that users might actually bother reading those numbers out loud to each other.
