GoKawiilDHH says he's stepped back from hand-coding, embraces LLMs and Rust at 37signals
At Rails World 2026, David Heinemeier Hansson said he has retired as a professional programmer, calling himself a 'maker' who directs LLMs to write code in English rather than reviewing the output line by line. He said 37signals' next version of Hey will use LLM-generated Rust on the backend and native apps on each platform instead of the Rails-based web stack he has long championed, and claimed to have produced roughly 150,000 lines of code in August versus about 30,000 lines a year previously.
