The Post-Quantum Cryptography problem is OUR version of the Y2K problem.
POST-QUANTUM CRYTOGRAPHY The need to switch out our cryptography to post-quantum cryptography is our modern 2020s version of the Y2K problem. They saw that problem coming several decades ahead of time, getting closer and closer, becoming more and more urgent. So, too, are we seeing the coming cryptographic apocalypse by quantum computing. But this time...we do not know the specific year. We just know it's coming.
