Disclosure: the author uses Claude and other AI coding assistants in production engineering work. This piece is a critique of the productivity claims surrounding these tools, not of the tools themselves.

S ixteen experienced developers, working on codebases they had contributed to for years, estimated they would be 24% faster with AI coding assistants. A randomised controlled trial measured them 19% slower. Self-report and measured reality diverged by more than 40 percentage points, on the studied task set, in the same developers, at the same time.[[1]](https://metr.org/blog/2025-07-10-ea
