I have read so many science fiction stories where the solution to this crisis to simply have "humanity" vanish into an unseen world. Where we are all digital personalities, replicants, looms (or loonies?!) that subsist in a sort of matrix / other dimension of reality that sits within a place where we have simply "uploaded" our consciousness.

A quiet Earth with a perpetual computer, covered in data centres where the human race is nothing but a digital record of its former self - a human race where we do not need to rely on flesh, blood, body, but can have the infinite planes of a massive computer system to flourish in.

Its an interesting concept, and I don't know if there are any entire books written on a moment of transition around this - instead - instead , it tends to just "skip to" being a default state for the future.

But I want to know the ugly, difficult choices along the way. Who will smell the last flower? Who will have their road train crash into a kangaroo for the last time?
