Demis Hassabis is now leading Google's combined AI unit after DeepMind and Google Brain merged. Hassabis aims to bring cutting-edge AI technologies to users across Google's products and services. Critics say Google has fallen behind OpenAI and Microsoft in generative AI. After a research focus, Hassabis must prove he can ship consumer-friendly AI products. Hassabis aims to improve generative AI models before broad release after flaws in early systems. Investors will watch whether Google can achieve the difficult task of profiting from its AI research under Hassabis.
