The law of death and dying is exquisitely sensitive to our notion of what it means to be human. When the crucial aspects of "personhood" are irretrievably lost, we feel that an individual has died. But what are those crucial aspects? Changes in the legal definition of death over time suggest that our sense of what is unique to the human experience alters as science progresses. This essay maintains that the next few decades may bring a dramatic change in our sense of human uniqueness and a corresponding change in the definition of death. The engine of change will be developments in artificial intelligence.
