## AI overview

A discussion with Addy Osmani examines the limits of AI coding. AI tools can quickly produce scaffolding and obvious patterns, but edge cases, security, debugging, and production integration remain difficult. The article also describes rising AI-code adoption alongside declining trust in generated code.

## Source excerpt

We hosted Addy Osmani, who works on AI and dev tools at Google's Chrome Developer Experience team, to talk about what he calls the "70% problem" in AI coding. Over the past two years, Addy has been tracking AI adoption patterns at Google, where over 30% of code is now AI-generated, and across the industry at conferences like Lead Dev. He's studied trust metrics, productivity claims, and what actually happens when teams scale agentic engineering beyond prototypes.
