+ We talk to Kevin Riggle (@kevinriggle) about complexity and safety. We also talk about the Twitter acquisition. While recording, we discovered a new failure mode where Kevin couldn't hear Thomas, but David and Deirdre could, so there's not much Thomas this episode. If you ever need to get Thomas to voluntarily stop talking, simply mute him to half the audience!
