Afterthought: the recent Pragmatic Engineer newsletter quotes that AI tool providers rely heavily on AI-aided coding. A thought crossed my mind, that maybe they are already tumbling into a downward spiral a declining code quality. At least that would explain why Windsurf, Cursor, and Claude performed so badly when I tested them last week.
”Today, 90% of the code for Claude Code is written by Claude Code(!),” Anthropic’s Chief Product Officer Mike Krieger says." Asked how the Windsurf team use their own product to build Windsurf, the team told them that “~95% of our code is written using Windsurf’s agent Cascade and the passive coding feature, Windsurf Tab,” and ”~40-50% of Cursor’s code is written from output generated by Cursor,” the engineering team at the dev tools startup estimated
