"Strong enough post-quantum schemes" already exist, and every single mainstream communications platform will update to become quantum-proof overnight if/when quantum computers approach that level of capability. Quantum computers cracking encryption is really not a concern on anyone's mind, at least no more than, say, modern processors cracking SHA-1 etc.

TIL! Which ones? I've only seen ones that were proclaimed to be secure, only to be broken in some simple/clever ways not much later.

There were a lot of pqcrypto candidates, and several of them were indeed thoroughly broken, prey to the fearsome cryptanalyst's laptop left running over a weekend

NIST standardized Kyber and Dilithium, and for now at least, they seem to be holding up. I'd still want to do hybrid (ECC+PQ) asymmetric crypto for the time being, but we're (slowly) starting to gain a modicum of confidence in the new standards, enough for deployment

You can basically just make the numbers bigger. Quantum computers aren't magic, and are still limited in what and how they can process within normal informational theories.

NIST post-quantum standards resulted from a 8+ year process and public competition: https://csrc.nist.gov/projects/post-quantum-cryptography
