Each column is a stretch of time in which the same views came up; a new column starts when one appears or goes quiet. Quiet means nothing on it in our sources for that stretch, which is not the same as a change of mind; Dropped means they said they no longer hold it; tap the card for which claim and when. Revised means the view carries on but one of its claims was dropped. Each row is one view, in the same place all the way along. The number is how many claims in that stretch; we hold 2 in 2025, 40 in 2026.
Widely available, open AI models are safer and more useful than closed ones, and AI is unlikely to end us

Armin RonacherCreator of Flask and JinjaMaybe I just read too much AI text now vs before, but I really feel like the model's ability to produce text I actually want to read and understand went downhill with newer releases.↗@mitsuhiko on Xx.com · 25 Aug 2026

Armin RonacherCreator of Flask and JinjaIt’s not very hard to make an agent somewhat durable. It’s surprisingly hard to make an agent harness inherently durable and not turn into a crazy mess.↗@mitsuhiko on Xx.com · 4 Oct 2026

Armin RonacherCreator of Flask and JinjaHot take for agents: there are situations were VMs work great, there are situations where sandboxes work great, there are situations where a durable object is all you need, and there are situations where you just need a javascript interpreter.↗@mitsuhiko on Xx.com · 11 Oct 2026
