You don't know what I do, and fortune 500 doesn't scream "excellent software engineering practices".
I also know some people at Google, and they are generally in the same boat as me - mostly using agents to generate code, but not blindly merging slop (yet).
30% of code merged without even glancing at it seems unlikely to me, but I can't disprove the number you pulled out of thin air. For side projects I bet it's far higher. For serious projects I have my doubts. It will get there, but it hasn't yet.
Google's own public number is 75% of new code AI-generated (April 2026), but that's engineer-approved, not merged without a look. Sources for that and other companies: https://xpoze.ai/ai-code-percentage
