A New Chapter for Google AI

Google’s artificial intelligence division is undergoing a significant transformation. In a move designed to centralize command and accelerate innovation, the search giant has announced a major leadership reshuffle. Demis Hassabis, previously the CEO of Google DeepMind, is stepping into a newly created role as Alphabet’s chief scientist while transitioning to chairman of DeepMind.
