For those who might like to see this concept explored more fully, I highly recommend Greg Egan's Permutation City [0].
To quote: “Paul struggled to imagine the outside world on his own terms, but it was almost impossible. Not only was he scattered across the globe, but widely separated machines were simultaneously computing different moments of his subjective time frame. Was the distance from Tokyo to New York now the length of his corpus callosum? Had the world shrunk to the size of his skull – and vanished from time altogether, except for the fifty computers which contributed at any one time to what he called ‘the present’?”
