Is this what you mean? What's the best way to do AES these days? AES-256-CBC? Is there "symmetric encryption" that is public key/private key? I know AES you just need IV + key and you're "good to go"?
I think he’s just implying that since asymmetric depends on the reverse operation being slow, there will eventually be a system fast enough or a non slow algorithm for the operation.
A bit far fetched IMO if the threat model depends on quantum computing but I have no idea about the subject so…
PGP? RSA? Can you elaborate please?
> symmetric encryption
AES?
