Microsoft AI CEO Mustafa Suleyman says healthcare is the most important application of AI -- and explains why the Mayo Clinic partnership matters. "This is why we create AI models. We want to do the best that we can in the world, make all humans healthier and happier and live longer." "We're going to have access to perhaps the most valuable, the most integrated, longitudinal patient data set in the world." Mayo Clinic CEO Dr. Gianrico Farrugia adds the real benchmark: "Most people will not have the opportunity to visit us... We can reach about 100 million people." "We're already seeing... diagnostic efficiency, but also to reduce the burden on our staff... [and ask] are patient outcomes actually better?" This is the health+AI lane that matters: not gadgets or admin hype -- model-guided medicine tied to real patient data, diagnostics, physician workflow, and measurable outcomes.
