DeepMind's Demis Hassabis is now chief scientist, signaling Alphabet's pivot from scientific AI research to commercial execution. Google, despite massive investment and breakthroughs like the transformer, struggled to monetize innovations; Hassabis reportedly prioritized pure science over market wins. This leadership shake-up, potentially empowering Koray Kavukcuoglu, addresses Google's chronic inertia and aims to accelerate product development. The company urgently needs an organizational overhaul to translate scientific prowess into competitive AI products, decisively shifting from research-first leadership to a market-driven strategy.
