Imagine there was a simple test to see whether you were developing Alzheimer's disease. You would look at a picture and describe it, software would assess the way you spoke, and based on your answer, tell you whether or not you had early-stage Alzheimer's. It would be quick, easy, and over 90% accurate--except for you, it doesn't work. That might be because you're from Africa. Imagine most of the world is getting healthier because of some new technology, but you're getting left behind.
