An incredible and inspirational talk by Tom Enden, with powerful ideas and outstanding delivery. I've watched it and then listened to it again a few days later on my commute, as it helped me frame some of my thoughts on how to build teams that can build software. As an example, "The world is the totality of facts, not of things" is why I believe safe (canary testing, blue/green deployments, low MTTR etc.) and fact-based testing of our software should be in production, where real customers can tell us the truth about the usage, usability, and stability of our propositions ("as truth-functions").
