Vibe coding is rewriting the rules — Two veteran engineers who helped build the internet explain why LLMs and AI coding may render the programming languages they spent decades building obsolete.

Keith Adams (HHVM, Facebook) and Julien Verlaguet (Skip Labs, ex-Facebook) go deep on how coding with AI is reshaping the craft they've spent decades mastering.

This isn't a surface-level AI hype conversation — it's a systems-level
argument about TypeScript's dominance, the hidden genius of linear types, c++, why reactive programming will be the next bottleneck, and whether Rust's borrow checker is the future or a dead end.

Computers, Coffee, & Beer is hosted by Keith Adams and Julien Verlaguet — two engineers who helped shape the modern internet and have the war stories to prove it.

Keith built the HHVM JIT compiler at Facebook, helped virtualize the world at VMware (employee ~80), and went on to Slack before founding Pebblebed, an early-stage VC firm for technically ambitious founders.

Julien created the Hack programming language, spent years writing safety-critical compiler software for Airbus and nuclear plants, and now runs Skip Labs.

Together they dig into the systems, languages, and decisions behind the technology that actually runs the world — told by two people who were in the room when it happened.
