Jon Gjengset spends about three hours livecoding complex changes in a Rust codebase with agentic AI tools, testing his hypothesis that AI is weak at non-pattern work. He documents where Claude Code helps and where it struggles.
Pointed to as a non-promotional, realistic long session of an experienced engineer working with AI on non-trivial code.
