SOMA is a horror game/walking simulator (depends on the critic) about a man who has his brain scanned as he is dying of brain bleeding caused by a car accident months prior. By having his brain scanned, it actually copies his consciousness, and he ends up transported to a far flung apocalyptic future.

I don't want to spoil too much, it's an amazing game with fantastic dives into rather dense and challenging ethical and philosophical questions. My reference to this post was about the fact that, in the future, an artificial intelligence fashioned a sort of "flesh nexus"—the AI was given the sole task of preserving human life, and in its reasoning, if a person is dying, they can be converted into something different that will live on indefinitely.

PLEASE, either go play the game (it's not extremely long) or watch a good let's play.
