Google AI, org charts and where real power sits

Koray Kavukcuoglu now runs Gemini’s model development and reports directly to Sundar Pichai. Demis Hassabis moves upstairs to chief scientist. Meanwhile Sergey Brin, by several accounts, has been coding, reviewing loss curves and sitting next to the Gemini team for months. No title. No reporting line. And yet half the coverage this week reads as if he just took over.

That gap between the org chart and the actual center of gravity is the more interesting story. Titles describe who is accountable. They rarely describe who people in the building actually listen to. A founder without a role can still reshape how fast a company moves, simply by showing up and asking uncomfortable questions in the right hallway.

Google has nearly every structural advantage in AI: researchers, custom chips, distribution into billions of devices, a budget most competitors cannot match. What it has struggled with is speed. Whether this reshuffle fixes that will show up in the product, not in the memo.

Worth remembering next time you assume a company’s real power sits wherever the title says it does.
