Google: 75% of New Code Now Written by AI

At Google Cloud Next 2026, CEO Sundar Pichai dropped a striking number: 75% of Google's new code is now AI-generated, with engineers reviewing and approving it. That's up from ~25% in late 2024 and 50% last fall — a 3x jump in under two years.

This isn't just autocomplete at scale. Google is shifting to agentic workflows where AI handles full migration tasks. Pichai noted one recent migration completed 6× faster than it would have with human-only teams. Engineers aren't out of the loop — they're becoming reviewers and orchestrators.

The rest of the industry is watching closely. Meta has set targets for 65% of engineers in its creation org to write over 75% of committed code using AI by mid-2026. The race to AI-native software development is no longer theoretical.

Why it matters: When the world's largest software company runs on 75% AI-written code, the definition of 'software engineer' is shifting in real time.
