Google is systematically reallocating capital away from frontier model development and toward compute infrastructure and data centers, which is why its top AI scientists are leaving to start new labs.
David Friedberg argues that Google's $200B capex commitment to AI infrastructure, combined with tax advantages from accelerated depreciation, makes infrastructure a higher-alpha, lower-beta investment than frontier model building — and that this capital-allocation decision, not creative destruction or startup allure, is what's pushing scientists like Jeff Dean and Demis Hassabis out the door.

David Friedberg: Maybe it's the third bucket, which is if you're the board and the management, you're having a debate about how to best deploy capital. Google has made a commitment to deploy $200 billion in capex this year in AI infrastructure data center buildout. Because of the capex and accelerated depreciation, making an investment in AI compute in the US right now is hugely tax advantaged. Building the most advanced frontier lab driven model also takes tens of billions of dollars of capital. And the question really is can you deliver the profits from the model? And in a world where open-source is becoming so good and open weights models are catching up so quickly... does it really make as much sense to deploy tens of billions of dollars against building a model? I think that the scientists that we're seeing transition out are the scientists that have been at the core of model development... So the way I would frame it is capex is high alpha low beta in data center infrastructure and that capital in model development theoretically could be high alpha but it's very high beta it's a very risky way to deploy capital. So if I'm the board I'm the management I'm deploying more capital in computing infrastructure less capital into model development that's what I think's going on.
