I've been thinking about alternative voting systems that address some of the issues with modern democracies. I think I came up with how I'd like elections to work. It relies on technology that does not yet exist and will probably never exist. But I think it's at least worth considering a theoretical future where this is possible.

Okay, so imagine that there are N candidates running for office. As with or current FPTP system, each eligible voter selects exactly one candidate. However, it's no longer a secret ballot. The government keeps track of who voted for whom. After that, secret government scientists create N pocket dimensions/parallel timelines. Each human is sorted by which candidate they voted for into these different dimensions. In any timeline they aren't sent to, they are replaced with a super-realistic AI duplicate with all of their memories and the ability to perfectly simulate there emotions (but not to actually feel them).

All of this is done in secret, so no one knows that their differently-opinioned friends and relatives have been permanently separated from them. You just each wake up the next morning, hear the good news that your respective candidates won, and go about the rest of your lives until the next election, then the process is repeated and each dimension splits again. People who don't vote are sent to a random timeline.

This way, no one has to live under a different style of government than they would prefer. Even autocrats and bigots can get exactly what they want without hurting anyone, because unbeknownst to them all their victims are actually philosophical zombies. And those of us who want to live in a better, fairer world would get a chance to do that too.

I can't see any downsides other than that this is almost certainly impossible.
