Boy oh boy. Well, the thing is it is a society that is completely in thrall to a system of basic pleasure orchestrated with the questionable justification that a life without real pleasure or pain is a better one. The people are oblivious to all art and real achievement, they have no desires and no ambitions, they create nothing and have no desire to, they feel no real emotions and all sex is mechanical, and they happily march to their own deaths at a certain age. If a vision of humanity as infinitely complacent, all advancement come to an end, a billion pampered babies with their unremarkable and entirely calculated lives engineered since before birth — if that doesn't strike you as a dystopia, an "inverted utopia" in which what is meant to be perfect is anything but, well brother, I don't know what should!
