Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 5,759 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 49 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Musk: There will be 5 to 10 frontier AI models globally
“I do think there will be several deep intelligences, maybe at least five maybe as much as 10. I'm not sure that there's going to be hundreds, but it's probably close, like maybe there'll be like 10 or something like that of which maybe four will be in the US.”
LLMs invert historical tech diffusion by reaching consumers before enterprise

Developers should build Iron Man suits, not fully autonomous robots

Blomfield: Embedding chatbots into software is almost always the wrong approach

“And you could see hundreds of millions of people displaced, and the idea that they're going to retrain as in a different job, I think is going to be extremely painful. And I can see the societal impact and turmoil being very, very grave for 10 or 20 years as t…”
Palicha: 10-Minute Delivery Has Better Economics Than 2-to-4-Hour Models
“The insight was, yes, let's do 10 minute delivery, but also let's build out the full stack of commerce where we're able to run the logistics, we're able to Have a much better sense and selection on quality control and sort of that audacious thinking Put us in …”
Palicha: 10-minute delivery in India is a necessity, not just convenience
“Now, obviously at scale, the insight is that it's not just important because people are used to it, but it's just, it's a necessity because you've got a lot smaller household sizes in India. You've got a low penetration of four wheelers. You've got much more p…”
Palicha: Indian startup ecosystem suffers from post-2022 fear and lack of ambition
“I think some of the hurdles are, as an ecosystem, I think we're, like, very much, like, post 2001 right now, because we had, like, a big reality check in 22, 23, and there's still a lot of fear and lack of ambition in general”
Thompson: Four Years After $42B Broadband Act, Effectively None Built

Thompson: Modern Failures Stem from Refusing to Update 1960s Institutions
“Institutional renewal is the charge of every new generation. And when we fail to update on the systems that we built 60 years ago, it's not their fault. It's ours. We're the ones deciding to live inside a building. That was built half a century ago that we ref…”
Xu: Suburban delivery economics beat cities due to family basket sizes
“Where in the places outside of city centers, the suburbs, you tended to have a greater percentage of families, which have more mouths to feed. As a result, you tended to have higher baskets. Higher baskets meant larger revenues. You also tended to have easier …”
Field: Software developers will soon call themselves designers

“I think one of them that I can read verbatim is, I think the role of software engineer will transition to product engineer. Human taste is now more important than ever as CogenTools make everyone a Tenex engineer.”
Friedman: Cheap AI makes developers rewrite code rather than debug it
“Like it's wild how your coding style changes when actually writing the code becomes a thousand X cheaper. Like as a human, you would never just like blow away something that you'd worked on for a long time and rewrite it from scratch because you had a bug. You…”
Hu: YC founders rarely use Devin for serious features
“Notable, Devon does get mentioned, but the drawback of Devon not really being used for serious features is that it doesn't really understand the code base. It's being used mostly for small features and barely, it's like barely mentioned.”
Hu: Vibe coding works for zero-to-one, but scaling requires systems engineers
“Zero to one will be great for vibe coding where founders can ship features very quickly. But once they hit product market fit, they're still going to have a lot of really hardcore systems engineering where you need to get from the one to N and you need to hire…”
Hu: Top 1% engineers will still require deliberate practice despite AI
“I think there's gonna be a generation of software engineers that are, like, good enough because it's so easy to retool there with all these cogent tools. Like, the barrier is so low. You're gonna be good enough engineers. There's gonna be tons of those. But to…”
Friedman: AI coding agents will bullshit founders just like human employees

Google cannot replicate Perplexity directly on its cluttered search homepage

Alströmer: Post-2020 easy capital killed startups that otherwise would have succeeded
“It's very clear that, that what happened in those two years after summer, 20, 20 hurt companies. Like, it was much worse than just, like, more of the same. It hurt companies that otherwise would have been successful, because they would have had a level of disc…”
McGrew: Nobody believed next-token prediction would work before GPT-1
“And the core idea behind GPT-ONE is that if you have a transformer and you apply this super simple objective of guessing the next token, guessing the next word, that that would be enough signal that you could actually have something that would be able to gener…”
