The XP Unconference brought practitioners together to wrestle with the hardest questions in software development — not in keynote-polished form, but in the messy, honest, hands-on way that the XP community does best. While this was the first edition of the conference, many familiar faces from the XP and Socrates/Software Crafter communities attended, and like usual, practitioners wrestled with hard problems. This year, the wrestling partner was unmistakable: AI had taken the mat.
Across two days, roughly 60 participants filled six rooms at a Berlin venue, self-organizing into 30 sessions that covered everything from acceptance test-driven development with AI agents to the ethics of energy consumption, from meditation techniques to whether software engineers need a union. The keynote by Dave Farley — "The Future of Programming with AI: Acceptance Testing as 5GL" — set the tone, but the real substance, as always, came from the sessions.
What follows is a synthesis of insights from all 30 sessions, organized by the themes that cut across them. This is not a session-by-session recap. It is an attempt to capture the collective intelligence of the room — for those who were there and want to remember, and for those who were not and want to learn.
