Anthropic hosted its annual developer event, Code with Claude, in London on May 19, the same day as Google’s I/O. During the event, Jeremy Hadfield, an engineer at Anthropic, asked the audience how many had submitted a pull request fully written by Claude. Almost half of the attendees raised their hands. Pull requests are essential updates to software that developers typically write manually. When Hadfield asked who had submitted a pull request without reading the code, the room filled with nervous laughter, yet most hands stayed up. This reflects the increasing reliance on AI tools like Claude Code and OpenAI’s Codex to automate coding tasks. Anthropic claims most of its software is now written by Claude, and similar claims are made by other companies like OpenAI, Google, and Microsoft. The event, now in its second year, saw developers from San Francisco and Tokyo participate. Last year, Anthropic released Claude 4, which could code, but recent updates to Claude 4.6 and 4.7 have made the tool more appealing to developers. Boris Cherny, who leads Claude Code, emphasized that the goal is to let Claude handle its own corrections, reducing the need for human oversight. Ravi Trivedi, another engineer at Anthropic, described the approach as 'Let it cook.' A new feature, Claude Managed Agents, allows agents to write notes for future tasks, improving efficiency. Companies like Spotify and Delivery Hero have integrated Claude Code into their workflows. Despite the enthusiasm, some developers express concerns about the impact on code quality and security. *Source: [mittr](https://www.technologyreview.com/2026/05/21/1137735/anthropics-code-with-claude-showed-off-codings-future-whether-you-like-it-or-not/)*
