How Jev Turns AI Into Software That Gets Things Done

a16z’s Ben Horowitz and Martin Casado sit down with TypeSafe AI founder Diogo Almeida to ask a simple question: AI has become remarkably capable, so where is all the automation? Diogo argues that coding agents may help us write software faster, but the software they produce still largely works the way software always has. TypeSafe is taking a different approach with Jev: putting intelligence inside software itself, so developers can build programs that reason about intent and make probabilistic decisions rather than simply generate text for a human to interpret. They discuss why reliability is the key to making AI genuinely programmable, how this could open a new era of probabilistic software, and why established SaaS companies may be particularly well positioned to benefit. Ultimately, Diogo’s goal is straightforward: technology that can reliably “do what I mean.” Timestamps: 00:00 - Intro 00:50 - Meet Diogo and Type Safe 04:07 - Smart software, not just faster code 15:46 - Where's all the automation? 22:00 - Is it just a data problem? 30:21 - SaaS apocalypse, reversed 34:58 - New capabilities, not more code 38:27 - Apps vs the guts of systems 41:08 - Reliability and "do what I mean" Resources: Follow Diogo Almeida: https://x.com/CompleteSkeptic Learn more about TypeSafe AI: https://typesafe.ai/ Follow TypeSafe AI: https://x.com/typesafeai Follow Ben Horowitz on X: https://x.com/bhorowitz Follow Martin Casado on X: https://x.com/martin_casado Stay Updated: If you enjoyed this episode, be sure to like, subscribe, and share with your friends!
