>Pretty much the whole cryptography field has been saying PGP is broken for something close to a decade now; the attack published today is an applied refinement of theoretical tools we've had for a very long time.

Yes. But unless I've missed something no one has bothered to even attempt any modernized, improved replacement, so we continue to muddle along. I've certainly heard complaints about existing secure email technologies for well over a decade, but at the same time the cryptography field has never offered an upgrade. Instead it's always been "completely give up on the concept of email (which in no way needs to be insecure) for these modern hip non-federated often proprietary clunky slow kitchen sink instant messenger things instead". To which the answer has and continues to be "no".

Maybe we live in a world where the creation and upgrading of a technology like email is no longer feasible and that's just how it is. If so though I foresee email as it is existing into the foreseeable future, and in turn it'll be useful to have some sort of crypto bolted on top, as a marginal improvement vs entirely plain text. Hopefully there will be enough security oxygen that OpenPGP could at least modernize the foundations a little even if it meant some breaking changes to old implementations.
