When I was in the hospital and saw so many various types of suffering, all I could think about was how technology and AI will eventually help with it! Anything around health is the field to be in with AI. I promise you it's not oversaturated. And I promise you, even if it seems like it's not important, it is. Eventually disability will catch up to us all, if it's in old age you are lucky. What good is living forever if you could suffer and become ill any day?
