Utopia: Involuntary suffering is successfully abolished. Technology that enables it's controllable inhibition is freely available for all personhoods.
Dystopia: The perversion of paradise engineering technologies for the creation of horrific weapons and torture devices, for instance; a (infinitely indestructible) nanosuit that incarcerates the body and paralyses it. Nanoprobes from the suit invade the body and it's systems in order to inflict the maximum (infinite?) amount of physical and mental pain upon the victim whilst keeping it alive indefinitely (infinitely?). Said suit for an infinitely more horrific version of locked-in syndrome that could never be broken free from.
Weirdtopia: A benevolent, negative utilitarian dictator AI uses time travel in an attempt to prevent the creation of all life in order for all suffering to never occur.
