From TFA: "The policy reflects growing concern about Harvest Now, Decrypt Later (HNDL) attacks, in which adversaries intercept and store encrypted communications today with the intention of decrypting them once a cryptographically relevant quantum computer (CRQC) becomes available."

Once it gets to be "later" where the harvest data is able to be decrypted, I guess will have decent enough LLMs to summarize all of that data? Otherwise, there's going to be such a huge back log to make it not too useful
