In my (admittedly anecdotal) experience, democracy rarely seeems to come to any consensus that is acceptable to everyone, but rather serves as little more than a moral battering ram that the 51% can use to impose their will on the 49%. Perhaps one day people will realize that democracy, given its cultish appeals (e.g. "but don't you know other systems are worse!?") is simply barbaric.
Maybe technology will render nation-states obsolete within my lifetime. I can only hope.
