Head of Claude Code: What happens after coding is solved | Boris Cherny

with Boris Cherny, Head of Claude Code at Anthropic

Claude Code has solved software engineering in less than a year—Boris writes 100% AI-generated code and ships 10-30 pull requests daily without editing a single line by hand since November. The next frontier isn't coding but having AI identify what to build by analyzing user feedback and telemetry, fundamentally shifting software roles from "engineer" to "builder."

Boris Cherny
“100% of my code is written by Claude. I have not edited it a single line by hand since November. Every day I ship 10, 20, 30 pull requests.”
Boris describing his current coding workflow and the scale of his productivity
Boris Cherny
“Coding is virtually solved. I imagine a world where everyone is able to program. Anyone can just build software anytime.”
Boris on the broader implications of Claude Code's capabilities for the industry

“by the end of the year everyone's going to be a product manager and everyone codes. The title software engineer is going to start to go away. It's just going to be replaced by builder and it's going to be painful for a lot of people.”
Boris predicting the transformation of software engineering roles due to AI

“At Anthropic over the last year, like since we introduced Quad Code, we probably like 4x the engineering team or something like this. But productivity per engineer has increased 200%”
Boris explaining the paradox of hiring more engineers while massively increasing per-engineer productivity

“Claude is starting to come up with ideas. So Claude is looking through feedback. It's uh, looking at bug reports. It's looking at, um, you know, like telemetry and and things like this and it's starting to come up with ideas for bug fixes and things to ship.”
Boris describing the next frontier: AI moving from writing code to proposing what should be built

Boris Cherny is the Head of Claude Code at Anthropic, leading the team that built the AI coding assistant that now generates 4% of all GitHub commits globally. Previously, he worked at Meta/Instagram as one of the top most productive engineers and led code quality initiatives across Facebook, Instagram, and WhatsApp. He briefly left Anthropic to join Cursor but returned within two weeks after realizing his core motivation was Anthropic's safety-focused mission.
1
**Coding is officially solved** Claude Code now handles 100% of code generation for senior engineers like Boris, who ship 10-30 PRs daily without hand-editing. At Anthropic, the 4x team expansion coincided with 200% productivity gains per engineer—a transformation that took less than a year and is now accelerating industry-wide.

**AI ideation is the new bottleneck** With code generation solved, the constraint has shifted to deciding what to build. Boris uses Claude to scan feedback channels, bug reports, and telemetry to surface priorities and propose features, automating the product discovery process that humans previously owned alone.

**Underfunding teams forces better AI leverage** Boris's principle of intentionally staffing teams lightly forces engineers to maximize Claude's capabilities rather than add headcount. This scarcity creates intrinsic motivation to delegate more work to AI, delivering faster shipping velocity with fewer people than traditional approaches.
