Scala Was an Experiment That Changed Programming - Martin Odersky | The Marco Show

Scala started as an experiment. Then Twitter adopted it, Java copied its ideas, and it went on to influence modern programming languages for the next 20 years. In this episode, Marco talks with Martin Odersky (creator of Scala and one of the key people behind Java generics) about Scala, Java, functional programming, AI-generated code, programming language design, and why AI agents may require entirely new safety models.

Disclaimer: We recorded this episode in a different studio, and the video quality didn’t quite meet our usual standards. We did our best to rescue it with AI in post 😬 We still think the conversation was too good not to share.
