This is JP Aumasson, the co-author of BLAKE2 and BLAKE3. Aumasson is notorious in cryptography circles for his "too much crypto" argument, that modern symmetric cryptography is overly conservative, running more rounds than are necessary given the very low likelihood that advances in computer science are going make a real dent in them.

A distinction a lot of comments in this thread aren't picking up on is the mechanisms that make most asymmetric cryptography work, versus those of symmetric cryptography. Asymmetric constructions like RSA and ECDH are simple mathematical objects, and their security depends on assumptions we make about advanced algebra, number theory, &c. It's plausible to imagine we could discover something about discrete logs that would destabilize DH. It's less plausible to imagine something like that happen to AES, which is deliberately designed not to have clean structure.
