This guy is nuts (TypeScript Doom)
Dimitri Mishunov-style madness: running Doom entirely in TypeScript types with zero JavaScript, then building TypeSlayer in Tauri to diagnose type performance. Plus SquiggleConf, JavaScript 1.0 on Windows 95, and AI anxiety.
#969
Scott and Wes sit down with Dimitri Mitropoulos to explore the wild edges of TypeScript—from running Doom in the type system to building tools like Typeslayer. They dig into Turing-complete types, performance limits, and what the future might hold for TypeScript and programming languages as a whole.
