...which is something I actually consider. It does indeed actually bother me that very few companies have actually adopted post-quantum cryptography yet. What is even the point of my VPN, for example, if there is a potential that everything is cracked 40 years down the line? NIST has already basically approved the standards. It should be an option for sensitive things, like anything to do with banking, data storage, and VPN.
Oh, I agree, it's definitely important. But that's sort of where the grift comes in. You mix the valid concerns with fear mongering and upcharges. I use ecc (or whatever it's called) for my ssh keys, not RSA.
I believe ECC is also targetable by quantum computers in theory. Post-quantum cryptography is lattice-based ciphers like Kyber.
