this is a remarkable essay. At a time when our behavior is being transformed by technology, we all need to give considerable thought to the negative implications of those changes.

This is a quick read and quite thought-provoking. Although it is from the Harvard Business Review, it could just as well be delivered at a homily at Sunday mass.
