Anthropic’s top engineer Boris Cherny has spent months predicting the end of software engineering as a job title. Now he’s using his own employer as exhibit A. The Claude Code creator says Anthropic has already crossed the line he’s been drawing for the rest of the industry—no one there writes code by hand anymore, not the engineers, not the product team, not him. He hasn’t touched a line himself since November. And unlike most executives making sweeping claims about AI’s potential, Cherny isn’t talking about what’s coming. He’s describing what already happened.What makes this more than a talking point is what’s happening beneath the surface. At Anthropic, Claude instances don’t just assist engineers—they talk to each other over Slack, run in autonomous loops, and resolve problems across teams with little human input. The company’s own AI tools have effectively replaced the internal workflow that most of the tech industry is still racing to automate. “There’s no manually written code anywhere at the company,” Cherny said in a recent internal talk.
Google , Meta, Amazon and every other Big Tech company are moving the same way
The rest of the industry is closing in fast. Google now says 75% of its new code is AI-generated, up from just 25% in late 2024. Meta has mandated that 65% of engineers in its creation org—which builds Facebook, WhatsApp and Messenger—generate more than 75% of their committed code using AI in the first half of 2026. Snap has set a company-wide floor of 65% AI-generated code. Amazon, after months of internal frustration from engineers blocked from using Claude Code in production, has now formally rolled it out to every corporate employee through AWS Bedrock.Cherny also believes the IDEs engineers have relied on for decades—VS Code, Xcode, Vim—are next to go. Claude Code was built as a terminal-based CLI with no graphical interface because the team could already see how fast the models were improving. Investing in a rich UI felt like building sandcastles. “There’s a good chance by end of year people aren’t using IDEs anymore,” he said.
The ‘software engineer’ title is dying, and Cherny says Anthropic is the blueprint
Cherny’s argument, laid out on Lenny’s Podcast, is that “software engineer” gets replaced by “builder”—someone who directs AI and thinks across disciplines rather than writes code line by line. Anthropic, where no one writes code manually and Claude agents handle the rest, is essentially the live demonstration of that thesis.But Anthropic’s own 2026 Agentic Coding Trends Report adds an honest footnote: while engineers bring AI into roughly 60% of their work, fully delegated tasks still sit at just 0–20%. Even Cherny reviews every line Claude produces. “I don’t think we’re at the point where you can be totally hands-off,” he admitted—a telling caveat from the man who declared manual coding dead.
Anthropic’s CEO Dario Amodei agrees, and so does company’s hiring page
CEO Dario Amodei has framed this as the “centaur phase”—a brief window where humans and AI work in tandem before AI pulls further ahead—warning that 50% of entry-level white-collar jobs face disruption within five years. Cherny is saying the same thing, just from the inside. At Anthropic, the software engineer as the world knew it is already gone. What’s replaced it is something closer to what Cherny keeps calling a builder—someone who knows what to build, not how to type it out.
