Ep 196 – Health in the Google Era: The Future of Health Technology Consumerism and AI to Empower Billions to Thrive, with Dr. Karen DeSalvo

The future of health will be shaped by consumer expectations for a mobile-centric experience with personalized insights and care services.  Information is determinant of health, where people already search for health information on Google hundreds of millions of times a day. Additionally people view YouTube videos about health conditions 100 billion times globally in a year. As consumers seek information ubiquity in their online experience, health information will also become more personalized through wearables and other mobile devices.

Our future in health will also be enabled by AI. Artificial Intelligence has the potential to transform the health of people on a planetary scale akin to the discovery of penicillin.  If developed boldly and responsibly, AI will be a powerful for health equity on a global scale.  It will also bring the joy back to practicing medicine by reducing cognitive burden and giving providers more time to spend with patient.

In this week’s episode, we explore health tech consumerism and AI enablement with Dr. Karen DeSalvo, Chief Health Officer at Google. Dr. DeSalvo is an internist and health leader working at the intersection of medicine, public health, and information technology.  She has dedicated her career to improving health outcomes for all with a focus on solutions that address all the determinants of health.  Dr. DeSalvo continues to be a powerful voice and advocate for eliminating inequities and improving the public’s health.  Under her watch, Google has optimized search and YouTube to better answer common health questions, updated its consumer health wearables to function more like medical devices and built artificial intelligence products to meet industry demands.

This episode covers various topics in the realm of healthcare technology innovation from consumerism, Generative AI and LLMs, health equity by design, and various initiatives underway at Google to connect and bring meaning to health information. In the interview, we also discuss the role of technology in mitigating the health impacts of climate change and addressing the epidemic of loneliness and isolation at a global level.
