Microsoft is increasingly favoring Claude Code, an AI coding tool developed by Anthropic, over its own GitHub Copilot for internal use. The company is encouraging thousands of employees to use Claude Code, even if they're not developers, to prototype ideas and speed up mundane tasks. This shift may lead to a future where more autonomous AI agents are creating code, potentially changing the role of software engineers. Microsoft's decision to adopt Claude Code internally may also impact its sales strategy for GitHub Copilot.
