Posit, for the sake of argument, that we get to the point where technology is not the bottleneck. Whether it turns out to be nanobots, the Holodeck, or just Ray Kurtzweil tapping into our cyber-transcribed brain circuits to say “I told you so” in his singular way.
In any case, suppose we can do anything — transport ourselves instantly, acquire unlimited possessions, live forever, read each others’ minds if we wish. What would we, as humans, do with all this?
Would we be able to live in a world utterly without limitations? Or would such a reality simply fry our brains, being the very opposite of the sorts of situations that human minds evolved to cope with?
Perhaps we would inevitably rebuild all of the problems humanity currently faces — war, famine, crime, prejudice, disease — simply because that is the only sort of reality in which our human need to solve problems makes any sense. It may be the only sort of reality in which we feel sane.
You can ask this question for yourself: Would you want to live in a world without limits?
