Python Is Not Enough: Why Pythonistas Are Falling in Love with Rust
In this episode of complexity.fm, hosts Bas Steins and Michal Martinka sit down with Bob Belderbos — Python veteran, educator, and coach with over 20 years of software development experience. Bob shares his journey from Sun Microsystems sysadmin to co-founding PyBites, to now coaching developers one-on-one and in cohorts on Python, agentic AI, and Rust. We dive deep into why the Python community is increasingly drawn to Rust, what AI is really doing to how developers learn, and whether vibe coding is a superpower or a trap.
