Ban linear algebra, probability & statistics, and vector calculus.
Top of the Democratic agenda on day 1 needs to be a pause on advanced AI development, regulation of this out of control industry, and a ban on artificial superintelligence.

Normal inclusive moderates are the face of the Democratic Party. Anything leftists touched *trailed* behind. By a lot.
It's not just Democrats winning: it's fresh, younger, more populist Dems. I really hope they become the face of the Party - now.

National GOP operative tells me: "People will try to overcomplicate this, but its really simple: This is 100% because of Iran. It's all in the data and has been since a week after the war started. The economic anxiety is directly correlated with the war. We got our asses kicked because of it."

1. More billionaires are associated with less poverty. 2. Increasing billionaires per capita by ten fold lowers poverty by 43 percentage points. 3. Sweden has more billionaires per 10M people than the U.S. (34 vs 30) 4. Correlation is fairly strong (R-squared of 0.6 for two variable cross-section data) 4. Since the graph is only a correlation, what do you think is the cause? πŸ”—in🧡

A CVE (Common Vulnerabilities and Exposures) is a publicly disclosed security flaw. They increased following a slight upward slope all the way to early 2024, when there was a sudden small increase... then starting in 2026, we went full exponential. In most instances, the vulnerabilities were pre-existing, so much of the increase is just our better ability to find the faults. This is of historical importance. We have never witnessed anything of the sort.

If only there was some way to see what it would have looked like if Chiang had won. Some island where we could have run a natural experiment. Personally I think they would have become a first world economic powerhouse of critical importance in AI & advanced technology.
If Chiang Kai-Shek had won, today China would be utterly poverty-stricken, have zero nuclear weapons, and would probably be host to a lot of U.S. military bases

I don't know about 10 but 2-9 are alive and well and I like to believe many Americans still (rightly) believe in 1
I asked 50 Japanese people, ages 9 to 91, one question. "What do you admire most about Americans?" Here are the top answers. 10. "They clap when the plane lands." (Office worker, 34) 9. "They say 'I love you' every time they hang up the phone. Even men. Even to other men." (Taxi driver, 61) 8. "A stranger told me she liked my shoes. Then she just walked away. She didn't want anything." (High school girl, 16) 7. "They thank the bus driver when they get off." (Bus driver, 55. He got emotional saying this.) 6. "They tell you their whole life story in the grocery line. I know about one man's divorce, his boat, and his knee surgery. We knew each other for four minutes." (My mother, 64) 5. "They stand for the anthem at a children's baseball game." (Little League coach, 47) 4. "When they lose, they shake hands and say 'good game.' And they mean it." (Sota, 12) 3. "They fly the flag on a regular Tuesday. No holiday. Just because." (Nurse, 28) 2. "They help a stranger push a car out of the snow, then leave without saying their name." (My cousin's husband, 52, who got stuck in Colorado once) And the number one answer came from the oldest person I asked. My grandfather. He's 91. He thought about it for a long time. Then he said: "They still believe tomorrow will be better than today." I asked him what he meant. "In 1946, we had nothing," he said. "The American soldiers I met were young and far from home. But they acted like the future was coming, and it was going to be good. After a while, we started to believe them." I asked him if he thought Americans still believe that. He nodded slowly. "Tell them," he said, "not to stop."

If you a millenial who loved The Next Generation and miss Patrick Stewart, I highly recommend watching Picard season 3. I saw it years ago and it's the proper ending this crew deserves. Very grateful to @TerryMatalas and folks for making it. You don't need to watch season 1 and 2, just go straight to season 3.

The climate case for the permitting reform bill is simple: Making all energy infrastructure easier to build will enable renewables to flourish β€” and erode fossil fuels' market share. And we have good reason to believe that's true β€” it's called Texas. vox.com/politics/508196/perm…

Check out the fascinating paper from @NEJM_AI: ai.nejm.org/doi/full/10.1056… I blogged about some of the highlights (and built interactive explorers for the underlying data) here: benjamintseng.com/2026/10/ai…
