Again, what you’re not clocking here is that it will be a very, very long time before we have sufficient quantum compute time available to engage in large scale decryption. Even just getting to the point where they can decrypt all newly generated messages will be a long time. By that point you’d have decades of historical messages to did through.
Barring some wild, out of nowhere leap forward in the feasibility, scalability and affordability of the tech, you’ll be dead by the time the NSA gets around to reading your old messages.
But they don’t have to dig trough all messages though. They can target specific people or organizations. And the fact that there is a possibility that this happens within the next 50 years, is a concern for spy agencies and other organizations with sensitive data.
