Descriptions:
Boris Cherny, the creator and engineering lead of Claude Code at Anthropic, gives a detailed account of how the tool evolved from an internal side project into one of the fastest-growing developer tools in the industry — including the internal debate at Anthropic about whether to release it publicly at all. Before joining Anthropic, Cherny spent seven years at Meta leading code quality across Instagram, Facebook, WhatsApp, and Messenger, and was among the most prolific code authors and reviewers at the company.
The interview’s most concrete section covers Cherny’s current daily workflow: shipping 20–30 pull requests per day with zero handwritten code, with Claude Code running on Opus 4.5 authoring 100% of every PR. He walks through how code review has fundamentally changed in this model — including a spreadsheet-based pattern-tracking system he developed at Meta that he’s adapted for AI-era review — and addresses how teams maintain quality when no human writes the underlying code.
A central metaphor running through the conversation is the printing press: Cherny argues that just as the scribes of the 1400s didn’t disappear but transformed into writers and authors as the market for literature expanded, AI coding tools will create new categories of builders rather than simply displacing engineers. He also directly engages with Andrej Karpathy’s observation about feeling more behind than ever as a programmer, offering a grounded perspective on which engineering skills are increasing in value — system design, taste, direction-setting — and which are declining.
