Can You Trust It? (One Day, 140K Downloads) | Isaac Gerber S2E12 | CausalBanditsPodcast.com
Send us Fan Mail How do you trust causal inference code that no human has read? On New Year's Day this year, Isaac Gerber was a little bored. A week later he had shipped diff-diff, a difference-in-differences library that has since crossed 140,000 downloads, built almost entirely by AI agents. In this conversation we get into how he makes causal inference software he can actually stand behind, even when he never reads the code. In this episode, we cover: How Isaac built diff-diff, a difference-in-differences library, in a single day (now 140,000+ downloads) A five-step workflow for building causal inference software you can actually trust Why he builds with one model family and validates with another How silent failures, like quietly dropped covariates, slip into AI-written code, and how to catch them Why verification, not writing code, is becoming the real bottleneck Enjoy the episode! ------------------------------------------------------------------------------------------------------ Video version available on YouTube: https://youtu.be/O53Ra0iIFp8 Recorded on Apr 28, 2026 in New York, USA. ------------------------------------------------------------------------------------------------------ About The Guest Isaac Gerber is a data science leader focused on causal inference methodology and the open-source tooling around it.
