Did the world end with any previous one breaking?
It’s incredible and awesome if AES GCM has a flaw found with an AI now, Chacha20 could be a direct or nearly-direct replacement.
The sooner a cipher breaks, the better.
I don’t doubt that we could come up with new crypto algorithms equally as fast, but how do you trust that they are resilient (or even just implemented correctly) without an extended vetting period?
Ima stop you there. Instead, you might be happy to be aware that outside of AI concerns, “quantum safe” (or assumed so) ciphers are all the rage. So this is already a likely solved problem with the next generation of encryption… until this are AI models running on quantum machines I guess!
