How do you know this? Whats the reference? My thinking is different and based on intuition.
I consider
the body as the conductor of consciousness, not the creator. This realm needs a "vehicle" in order to interact and manipulate its elements and the Earthday Suit wrapped around your unfinite awareness is this. Without it you're a hungry ghost, just floating around. We currently create the shells via organic birth but its easy to see that with the tech to move mind to a neural net we can become artificially immortal with extended lifespans as we conquer death by shifting mediums. Its a Game, after all, this is just the next levels DLC that is yet to be revealed. Consciousness is everything. Your Souls is the credit you inserted to play.
Download that into a new physical frame as and when needed and its obvious you'd engineer something that looked like a human but stripped to its basics as it wouldn't need to process food, grow. reproduce etc... There would be no hair, the flesh would be frail as they are "disposable" in that respect as you'd wear it like threads, hence Earthday Suit works best. They don't need to fight the elements with such a mastery of tech and the brains would be larger to superconduct a higher rate of consciousness.
End result?
Intergalactic set tripping, cuh!
