   DHH's dramatic shift from AI skepticism to full embrace of agentic engineering

   • DHH describes his transformation from being skeptical about AI's role in programming 13 months ago to now being '100% AI pilled,' attributing the shift to Opus 4.5 released November 24, 2025, which was the dividing line where output quality became uncannily close to what he would have written himself.
   • He frames the moment using Lenin's quote 'there are decades where nothing happens and weeks where decades happen,' noting that decades of progress occurred in just nine months and comparing it to living through the Wright brothers' first flight.
   • DHH identifies three phases of the agentic age: the first where he had to drive and review everything, the second with sub-agents that subdivided tasks, and the current era with Opus 5, Fable, and GPT Sol where he tells the agent the problem and it tells him where to go.

   The evolution of AI coding tools and the November 2025 inflection point

   • DHH explains that pre-agentic AI was just a more efficient autocomplete and chatbot that didn't change his emotional connection to the computer, but agents starting around November 2025 fundamentally rewrote the rules.
   • He notes that Opus 4.5's key advance wasn't just raw intelligence but its ability to instrument the computer, use tools, and check its own work, making it genuinely useful for real work.
   • DHH describes how the Christmas break of 2025 allowed many developers at companies like Shopify to experiment with agents and have the same mind-blowing realization that this was a different genre of tool.

   AI's capability across different programming domains from web dev to safety-critical systems

   • DHH argues that for web dev CRUD applications, AI can write close to 100% of code, and he hasn't written any code by hand for Omarchy's Quatro release, though he still reviews the shape and critical model-layer lines.
   • He notes that AI is insanely capable at finding and fixing security vulnerabilities, citing the Fable model that was too dangerous to release because it could string together combo moves to achieve remote code execution.
   • For large existing codebases like Basecamp and Hey, DHH found agent acceleration surprisingly tricky, and in February 2026 they ended up with PRs that individually seemed fine but collectively destroyed the architecture, requiring manual cleanup.

Temel kavramlar

• agentic engineering— DHH's term for the new mode of programming where AI agents do most of the actual coding while humans steer with design and taste.
• Opus 4.5 dividing line— The November 24, 2025 model release that DHH calls the moment AI output quality became uncannily close to his own hand-written code.
• AI agents— Autonomous coding systems that shifted from curiosities to transformative tools within nine months.

Önemli alıntılar

• There are decades where nothing happens and weeks where decades happen. And we have seen decades of progress happen in the last nine months.

• I did it for 25 years. Like, I wanna see something new here, especially if we're all gonna live forever, which I hope we don't.

  — A counterintuitive lack of nostalgia from one of the world's best hand-coders about his craft being automated.
