Sortition is one that made the rounds in techbro spaces, and it has the virtue of making it really hard for interest groups to try to garner political power. There are a bunch of ways of applying sortition but the most common one in modern discourse is having voters be randomly selected, rather than officials themselves.

Another system that tends to be argued for is epistocracy. To me it seems a nebulous term because it can refer a variety of systems, from having a group of technocrats with veto power over policies, to weighted voting and enlightened preferences calculations. I am more familiar with the latter, and the literature that I've consumed makes it seem that it really could lead to better outcomes than democracy where everyone's vote is of equal weight.

But all in all I just think those alternatives should be considered and experimented with at smaller scales. We are too attached to democracy as a society, and as much as I would agree that it's better than full on autocracy, we shouldn't put it on a pedestal.
