I don't think anyone is necessarily okay with it, but there's not really any other option, right? If quantum breaks the cryptography currently being used by Nostr, then keys must be considered to be compromised, requiring you to start over with a new private key that is hopefully built on a quantum-proof standard.

Of course, every other form of social media and most other things would also be borked at that point, so...

We will all be dead when this happens. Not my problem hahaha
