What I argued in my @sfrubyconf 2025 keynote and expand on in this essay is that Ruby has been preparing us for the age of AI coding agents since the beginning. What XP taught us about feedback, coordination, pairing, clarity, and courage turns out to be exactly the skillset required when you’re no longer coding alone, but collaborating with a swarm of LLM-powered workers. The rituals we once used to stay aligned with human teammates now keep our agents grounded, coherent, and in sync with what we actually intend.
Agentic tools can generate more code in ten minutes than most teams shipped in a week a few years ago, but velocity is an amplifier, not a virtue. Without process, AI simply multiplies the mess. With structure from TDD, refactoring discipline, clear architecture, and conversations anchored in intent, the acceleration becomes liberating instead of destabilizing. CHOP (Chat-Oriented Programming) isn’t magic; it’s pair programming with a partner that never gets tired but absolutely needs your guidance, guardrails, and interruptions.
What surprised me most while writing this piece is how naturally Ruby fits this moment. The language’s long-held values like readability, expressiveness, humane design, and code that reveals intent are exactly what AI agents need to stay oriented. A clean method reads like a thought, a good abstraction reads like a story, and that clarity helps both humans and machines avoid drifting into confusion.
At the heart of it: architecture and developer experience are no longer luxuries. They’re survival tools. Invest in your environment. Invest in clarity. Leave the campsite better than you found it. Ruby was ready for this future not because it anticipated AI, but because it has always been designed for the kind of collaborators we must now learn to be.
I think this weekend is the perfect opportunity to work on update to the second edition of Kamal Handbook.
If you already have a second edition or a patron copy, you'll be first to get this free update.
If not, you should probably get it!
