"The Senior Engineer Death Spiral" - Ep 06

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.
