Hassabis told YC founders that the most defensible AI startups combine the AI wave with a deep technology domain — materials, medicine, atoms. These interdisciplinary bets require physics, chemistry, and biology expertise that no foundation-model update can replicate. Pure API wrappers get crushed by the next model release, but a team that understands both the ML and the domain science builds something frontier labs can't displace. He called these 'root node problems' that unlock entire branches of discovery.
