100% of Code at Anthropic is Now Written by AI
The way engineers work is changing fast. **Boris Cherny**, head of Claude Code at **Anthropic**, revealed that he hasn’t written a single line of code by hand since November. Not 90%. Not 95%. **100% of his code is generated by AI.**
In this video, we explore how Boris ships **10–30 pull requests a day** using **Claude Code**, while still reviewing every change to make sure it’s correct and safe. The typing is gone—but the thinking, reviewing, and system design remain.
This shift isn’t happening to just one engineer. Companies like **Spotify** are seeing their top developers rely heavily on AI tools as well. The tedious parts of coding—syntax errors, debugging, and small repetitive tasks—are increasingly handled by AI, allowing engineers to focus on problem-solving and building better systems.
Just a year ago, many people believed AI would never write real production code. Today, AI coding assistants are becoming a central part of how software is built.
Is this the future of engineering, where developers focus on ideas while AI handles the implementation? Or is this level of automation only possible for a small group of elite engineers?
Watch the video to see how AI is changing the role of developers and what it might mean for the future of coding.
