The Ledger
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 12 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 1 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

Anthropic Engineers Increased Code Output by Hundreds of Percent With Claude Code
“What happened with Claude is now many companies, including Anthropic, and all of our biggest customers are reporting gains on the order of hundreds of percentage points. And I think the last number that we reported is the amount of code written per engineer at…”
Cherny: Multi-Claude Automated Safety Checks Are Now Safer Than Human Approvals
“Essentially we found both in the laboratory setting, and now we're finding in the wild, this is safer than what we had before. So as a user, it's a really nice benefit, because you don't have to sit there and say yes over and over, and actually the result is b…”
Cherny: AI Agents Will Destroy Switching Costs as a Software Moat
“Some modes get less important, and this is, for example, switching costs, because if you want to switch from vendor A to vendor B, you can, you know, you can just ask Quad to do that, and Quad is going to get better and better over time at it.”
Cherny: AI coding models will eventually form a self-reinforcing loop
“Quad is starting to generate its own ideas for what to build next for QuadCode, but it's, you know, it's not always good ideas, and I still generate most of the ideas, and, you know, at some point it's gonna change. The model's gonna improve, and it's gonna be…”
Cherny: Claude Code was first AI tool able to edit local computer files

Cherny: Prompt chains will deepen, but humans will still pilot AI
“And at some point, Claude is going to become really good at asking Claude to do this. And that person is going to be asking Claude that asked Claude to do this. And this chain will just keep getting deeper, but in the end, you still need people that are piloti…”
Cherny: AI Commoditizes Code, Making Network Effects the Ultimate Business Moat
“One that I think will increase in importance is something like network effects, because it doesn't matter who's writing the code. It doesn't matter if it's an agent at the core of your product or something else, or if there's intelligence in your product. If t…”
