Today's guest is Stuart Caborn, distinguished engineer at loveholidays, which is an online travel agency with millions of customers around the world.

I'm talking with Stuart because his team is doing AI coding for real.

They operate an extremely complex product and technology, with each engineer deploying to production more than 80 times a month, with more than 60% of production code being written with AI, all while maintaining an absolutely elite change failure rate under 1%, and with perfect code health.

So, let's see how they pull this off.

Today’s guest is Chris Lattner, one of the most important engineers for modern computing. Chris invented key compiler infrastructure tech like LLVM and MLIR, but he’s also the inventor of the Swift language, a key contributor in bringing Google TPUs to market, and a lot more. Today he’s the founder and CEO of Modular, where he’s reinventing AI infrastructure to make software portable across GPUs and platforms.

So with Chris, we talked about his vision for AI and computing. We talked about how Modular’s mission makes us closer to a future where AI is open and portable. And we talked about open source, how AI is both empowering and straining contributors, how it’s changing intellectual property, and what workflows we need to change as engineers.

And finally, we discussed how AI is changing software craftsmanship, how he’s bullish about junior engineers, and a lot more.

Today's guest is Amelia Wattenberger, former principal research engineer at GitHub and now partner at Sutter Hill Ventures.

But she's also a product lead at Augment Code, where she developed Intent, a developer workspace for orchestrating AI coding agents and delivering complex work.

So this is a fascinating chat into the future and the present of software development with someone who has clearly been at the very frontier of this for many years.
