Google Engineer Shocked: Claude Code Does Year's Work in an Hour

• Google's Jaana Dogan revealed Anthropic's Claude Code replicated a year of complex system architecture work in just one hour.
• Claude Code generated a working prototype for distributed agent orchestrators from a simplified, public description, matching Google's validated designs.
• Dogan, a Principal Engineer for Google's Gemini API, found the AI's ability to navigate complex design choices independently "shocking."
• She noted AI's rapid evolution: from single lines in 2022 to full codebase restructuring predicted by 2026, capabilities she thought were years away.
• Google currently limits Claude Code use to open-source projects; Dogan sees competitor progress as motivation for Google's own AI development.

Why It Matters: Anthropic's Claude Code rapidly replicated complex Google architecture, highlighting AI's accelerating development.
