100% of Claude's code effectively AI-written: Anthropic CPO

According to Krieger, the engineering process at Anthropic has moved away from traditional manual coding faster than expected. He said staff engineers now ship pull requests ranging from 2,000 to 3,000 lines that are generated entirely by the AI. Under this system, human developers have moved toward high-level oversight and the verification of machine-generated code rather than line-by-line creation.
