This stuff is all very interesting but, unless you&#x27;re a researcher, has no immediate practical impact. What you would almost definitely accomplish by switching from (quantum cryptanalysis vulnerable) Curve25519 to a (supposed quantum safe) lattice or code-based algorithm is shipping something terribly insecure. It took a long time after the deployment of RSA, and an even longer time after ECC, to figure out the fiddly details of implementing it safely.
