Post-quantum or quantum-resistant encryption techniques exist today and are less pleasant to implement than legacy encryption methods, but there is insufficient reason not to implement them now because files and data being transmitted today could still exist and require decryption in the future when quantum computers arrive, making quantum-resistant encryption critical for national security purposes where classified information may retain relevance across decades.

“we should be trying to implement post-quantum encryption everywhere we can, not because we have quantum computers today, but because the files that we're moving around today could still exist at the future time that the quantum computer exists and then be used to decrypt all these files”
