Google's chief health officer, Karen DeSalvo, believes that AI will enhance health services, but acknowledges that there is still progress to be made. DeSalvo is optimistic about the potential AI offers for improved access to quality healthcare, but stresses the need for appropriate constraints, factual accuracy, ethical considerations, and equity in its implementation. While AI can address workforce shortages and enhance patient care, DeSalvo emphasizes that it should serve as a tool for doctors instead of replacing them.

She highlights the potential of large-language models (LLMs), such as Google's Med-PaLM LLM, for providing doctors with vast medical knowledge but also acknowledges the importance of human involvement in diagnosis and treatment. DeSalvo mentions the challenge of refining the models to ensure factual information and avoid misdiagnosis. Ultimately, the goal is to empower patients with information and place more control in their hands.
