I just watched "Decentralized Authentication is Our Only Hope" and the dude presented a new method of authentication that went over my head. Back when reading SQRL my first thought was "damn, that's genius".

My credentials lie pretty far from cybersecurity and I'm way out of date on auth (OAuth I understand, but not webauthn and FIDO, etc.), so if somebody could maybe explain why SQRL didn't catch on, that'd be great. Was it too complciated? Did something better come along? Just general inertia?
