@KAErdmann What’s the math on depreciation? Any tax rule that people point at as a huge benefit makes me suspicious. Seems like it would discourage selling even when otherwise optimal

Flexport France is hiring in Paris. Join us if you love global logistics and want to bring the world's most advanced supply chain technology to French businesses. And unlike the NBA, Flexport recognizes the Battle of Nancy and the legitimacy of the Valois Dukes.

@_____Lightning @jasoncrawford I guess the danger is if a human driver is behind an EV that stops so quick it’ll get rear ended and slide forwards.

Child steps into the street from behind an SUV, directly into the path of a Waymo going at 17mph. Waymo immediately brakes hard, but hits the child at 6mph. Child sustains minor injuries. Waymo calls 911 and remains on the scene until police arrive. Waymo employees also call NHTSA to report the same day. Waymo estimates that a human, even if not distracted, would have hit the child at 14mph: waymo.com/blog/2026/01/a…

@patrickc Haha, exactly 😅 Naming startups feels like Tolkien vs. reality now. Eventually, we’ll be left with stuff like GollumGPT or Smaug Analytics. Creativity will have to go way beyond just the name.

It's going to be tough for startups when all the Lord of the Rings names are taken and the only thing left is something like Bombadil AI.

@thogge Not to be a "well my predictions were accurate even though it seems they were completely wrong", but did the tariffs really take effect? It seems like they kept getting postponed and they were only chaos and uncertainty rather than real economic impact.

Earlier this year I was absolutely convinced the tariffs were going to cause a big recession. I tweeted about it a bunch. I was wrong.

ChatGPT seems absolutely 100% convinced it can send me PDFs through the web interface. Every time this fails it offers to tweak the formatting or print it with cut marks for lamination etc.

We could save a lot of our national reputation this year if Congress attached a ban on anything named after anyone still living to the next budget.

@sethbannon @alexisxrivas Child seats on planes is a good example of this. Removing lap infants will kill children, but they won’t be in planes when it happens.

It sounds strange, but some regulations make things too safe. Take commercial aviation: it’s 200x safer per mile than driving. A 500 mile flight every day for a year gives you a fatality risk of ~1 in 100,000 years of flying. Yet safety rules keep tightening. And that’s a problem. Why? Stricter regs → higher costs → fewer flights → more people driving → more deaths. So yes, regulations can make things too safe!

50 million people have walked the Guggenheim spiral. Zero fell over its 36" parapet. Today's code deems it unsafe, demands 42". When 50 million safe visits can't clear plan check, the real danger isn’t the parapet - it’s bureaucracy.

@DrPhiltill Not an academic, but three different approaches is way too broad. I’d buy a paper analyzing the agreement or disagreement from survey papers reviewing each of those approaches.

2/2 From Grok: Abstract
The landing of lunar spacecraft presents unique challenges due to the interaction between engine exhaust and the lunar regolith. This paper investigates the dynamics of lunar soil displacement caused by high-velocity exhaust plumes during soft landings. Through a combination of computational fluid dynamics (CFD) simulations, laboratory experiments using regolith simulants, and analysis of historical lunar landing data, we quantify the extent of soil erosion, crater formation, and particulate ejection under various engine thrust profiles and landing conditions. Our findings reveal that exhaust-induced soil blowing significantly alters the local surface topography, potentially compromising landing stability and contaminating nearby scientific instruments. We propose a novel exhaust diffuser design to mitigate regolith displacement, demonstrating a 40% reduction in ejected particulate mass in controlled tests. These results offer critical insights for the design of future lunar landers, ensuring safer landings and preserving the integrity of the lunar environment for scientific exploration. I aimed to craft an abstract that mirrors the style of a human-written technical paper—concise, precise, and grounded in realistic scientific language. The structure follows a typical abstract format: problem statement, methods, key findings, and implications. I included specific details like “40% reduction” and “CFD simulations” to enhance authenticity while avoiding overly complex jargon that might feel unnatural. Let me know if you can tell it’s AI-written or if you’d like me to tweak anything!

1/2 I tried it, asking AI to write an abstract in my field. I feel sure I could pick this out as AI-written because of the smarmy adjectives, excessively broad scope for realistic research project, and unrealistic technical solution. See what Grok wrote in part 2/2.

I've seen AI art, video, and even music that's indistinguishable for me from human counterparts. But it's easy for me to spot AI writing, esp if it's about menswear. Curious if this is bc I know that domain better. Can videographers spot AI videos? Or is writing more AI-proof?

@XPlaneOfficial guys what’s up with the new ATC? It keeps trying to give me vectors while I’m doing touch and goes. Can you at least add an option to turn it off?

@TheFIREorg I am helping my HS student research colleges, and the required email address in front of your rankings makes me think he won't actually log in to use that site. Your work would have broader impact if it were more accessible.
