Show Notes
Recorded September 21, 2026. Sunil and Rhys join the Jevolution. Sunil explains the Senior Engineer Death Spiral, the blog post that blew up his DMs (and annoyed capital-E Engineers on Hacker News). Rhys looks back on YC and shows off his latest workflow. And we definitely do not talk about AI safety.

Recorded August 7, 2026. We explore AI alignment & safety, Rhys demos his workflow, and we end up mentioning a lot of books.
Recorded August 3, 2026. We discuss burnout, Claudeisms sneaking into regular speech, chip butties, how to watch movies, and what brings us joy.

Recorded July 17, 2026. We settle the model-access bet. We talk about how the labs talk to us, plus extend an open invite for OpenAI, Anthropic, SpaceX, and Thinking Machines to come on the show and be specific about their best-case scenarios about how AI makes the world better. Thinking Machines ships an American open-weight model. And then Dillon fires the slop cannon, walking us through his agentic workflow, while a package he technically did not order shows up.

Recorded June 30, 2026, 2pm Pacific. Live from AI Engineer World's Fair! Fable is still banned (as of recording time, ahem). Advice: Build for agents. We're still talking about loops, but which loops? And more receipts are demanded.
