Reality check: • Pure theory. Zero physical qubits ran anything. • Clifford only. Not universal, magic states still required. • Distance scales as n^0.28, sublinear. Far from linear-distance good qLDPC codes. • "High-rate" is loose: k=√n means rate falls as 1/√n, not constant-rate. • Depth-1 is per-generator; an arbitrary Clifford is still O(r²) depth. But zoom out: The interesting fact isn't the code. It's the byline. NVIDIA is staffing real QEC theory (Krysta Svore's group), which is how you end up owning the quantum-classical software stack rather than just selling decoding silicon. Direction: the fault-tolerance fight is moving up the stack into compilers, codes, and control software, and @NVIDIA wants that layer. arxiv.org/abs/2606.13521v1

I got to spend all day today with Jensen in Taiwan: talking with thousands of engineers and eating street food at a night market. Jensen is received as a rockstar in Taiwan, like it's Beatles in the 60's. It's mind-blowing and fun to watch. But most importantly, through all the interactions and all my conversations with him, he remained the same humble, kind, thoughtful, funny guy he always was, even as a kid who went to these same night markets many years ago. Btw, we tried a crazy amount of different street food. It's legit some of the most delicious food I've ever had. I can't wait to share video of it, including a ton of our conversations and hangout. When I can pause for a moment from all the travel to edit the video, I'll post it. Can't wait to continue talking to Jensen and engineers at Computex this week, and exploring more of Taiwan, and of course roaming the night markets for some more delicious street food. Days like these, even more than usual, I feel like the luckiest kid in the world. Love you all! ❤️
