@mjos_crypto @CadeMetz This is a bit confusing because you could make the same statement about one-time pads being unbreakable. Shor's didn't make BB84 advantageous compared to classic cryptography.

@sweis Yeah. Try explaining (already confusingly-named) PQC when NY Times just says stuff like this☹️

Bennett and Brassard win the Turing award for BB84 quantum cryptography.
There’s going to lots of people confusing this for quantum computers *breaking* cryptography and post-quantum cryptography.

The security landscape is changing fast. I'm hiring people to figure out what comes next.
My team led this work — and we're expanding.

We partnered with Mozilla to test Claude's ability to find security vulnerabilities in Firefox. Opus 4.6 found 22 vulnerabilities in just two weeks. Of these, 14 were high-severity, representing a fifth of all high-severity bugs Mozilla remediated in 2025.

"Claude Opus 4.6 discovered 22 vulnerabilities over the course of two weeks. Of these, Mozilla assigned 14 as high-severity vulnerabilities"

The majority of security vulnerabilities going forward are going to be discovered by AI.

Now is a good time to say I'm hiring @anthropicai for the Frontier Red Team. We need Research Scientists on the biggest issues in model safety, like cyber, autonomy, and agent risks. 2026 is the year.
I can promise you your life's work and the most meaningful mission.

@sweis Really impressive. I’m curious how long it’ll be before models start generating genuinely new conjectures, not just proving ones we already have.
(It's wild that that's where the bar is right now)

Claude solved one of Donald Knuth's conjectures from writing "The Art of Computer Programming" and he wrote about it.

I am told that Claude demands a Knuth Reward Check:
