The 22-point traveling salesman problem appeared on last night's @colbertlateshow !! Sadly it still takes a 1000 years according to the @washingtonpost
To clarify, computing an optimal TSP route on 22 points takes 0.005 seconds on my iMac, not the 1000 years reported in @washingtonpost An error factor of 6 trillion. Like reporting the US National Debt is $4. https://t.co/pazNxcdmk2

LLM adoption among US workers is closing in on 50%. Meanwhile labor productivity growth is lower than in 2020. Many counter-arguments can be made here, e.g. "they don't know yet how to be productive with it, they've only been using for 1-2 years", "50% is still too low to see
LLM adoption rose to 45.9% among US workers as of June/July 2025, according to a Stanford/World Bank survey. Inference demand will continue to surge, not just from more users and more usage per user, but as newer, more advanced GenAI models require far more inference compute.

I see a lot of confusion about Google's Monday press release about quantum supremacy, so let me try to clarify a few things. They say they did a computation on a ca 100 qubit chip much faster than a conventional (super)computer could do. The particular calculation in question is
