    Also, we apparently already have theory in place for all kinds of cryptography that’s resilient against quantum computing prime factorization, so I don’t see the sky falling anytime soon. Not for that reason, at least.

      Yeah, it’s simply cryptographic algorithms that don’t use primes, and instead use for example elliptic curves.

      They’re still a bit in a weird spot, in particular only certain elliptic curves are secure, and to my knowledge so far only really US intelligence services have checked their security, so people are a bit worried that they declared elliptic curves as “secure” for which they have working exploits.

      It would also be nice, if we could switch over like a decade before quantum computing becomes viable for decrypting, so that they can’t decrypt recorded communication afterwards and still potentially extract passwords that are still valid and so on.

      But yeah, with all of that in mind, I don’t see quantum computing being a problem yet. It won’t be here for a while still and when it is here, it won’t either magically decrypt all communications over night.
