Rails Creator DHH Has Left the Coding to AI Since Around March
David Heinemeier Hansson, who has been writing code for 25 years, says he has not typed code himself since around March, reversing the anti-AI-coding stance he held a year ago.
David Heinemeier Hansson (DHH), the creator of Ruby on Rails, says he has stopped writing code by hand. According to a September 25 report by The Decoder, Hansson explained at the Rails World 2026 event that he has not typed a single line of code himself since around March. It marks a self-imposed break with a way of working he had kept up for 25 years.
Hansson said he finds it better to describe what he wants in English than to write code in the Ruby programming language. In other words, he places a high value on everyday language as the medium for telling a computer what to do. The remark captures just how much his attitude toward coding with AI has shifted.
Only a year ago, Hansson was opposed to writing code with AI. At this event, he called AI coding the single biggest change in the history of computing. His assessment flipped in a short span of time, and he pointed to his own experience of no longer typing code as evidence.
The comments stand out because they come from someone who built developer tooling and has now changed how he works himself. The open question is what that shift will actually mean on the ground in software development.
