I have recently thought about a possible future where everybody could kill everybody else anonymously. No idea how that would play out - probably with extinction? I think technology could provide such a future, for example something like those tiny poison drones in the movie Dune. Or maybe it will be possible to genetically engineer a virus to just kill one specific person - kind of like Stuxnet was targeted at one specific factory...
