I dont get it. I just don't get it. No one has ever payed attention to the wise words of A. C. Clarke: "They no longer built spaceships. They were spaceships."
Such is the great StarLab's belief. Everybody is ranting on about Ftl-travelling spaceships. What about humans, if we don't wipe each other out, gradually replacing our bodyparts with mechanical stuff, which is only beginning to happen today, what with mechanical limbs and 'pacers. After this, when humans completely leave the realm of flesh and blood (a good few thousand or million years), we, the 'machine-entities' as Clarke calls our future descendants, would "learn to store our memories in space-time itself." At this point, we would be masters of the cosmos, and Ftl travel would be a reality.
Clarke is the true Mashiach of SciFi.
