Cryptography doesn't solve social problems.

Cryptography doesn't solve political problems.

Cryptography solves communication problems. That's. It.

Being sure that it's really my son talking to me over the phone is primarily a communication problem, no? The social and political implications are quite large, but they can be addressed by solving the communication problem. This can involve crypto.

Or am I missing something?

(I say nothing for or against the particular scheme proposed by gp, just against parent's implied generalized dismissal of crypto to solve this problem)

Agree. I was just talking about a pure technical issue of voice synthesize, and its implications to voice encryption. In other words, a communication-over-the-phone problem. I didn't mention nor intended to talk from a political or social perspective.

While I understand the parent comment's stance that cryptography is not the magic sauce, I don't think it's related to my comment.

Cryptography can solve social problems, but the problems need to be approached from a social perspective, not a computer science perspective. There's a hint of this type of approach in the work of Keybase.
