Paul Farmer is a Harvard professor, the founder of Partners in Health, and a global leader in public health. In our current moment, a moment of health chaos, when each day brings news that seems unprecedented and frightening, Dr. Farmer's voice is a voice we need.  He urges us to think broadly about the meaning of technology, to think twice before we act too quickly to sacrifice quality for scale, and to know a place well enough that you can celebrate its progress over time.
