Do we limit "Beyond Human" to only carbon based life or existing forms of life? If not we can image why we need democracy.

The individual ego of carbon based life are not easy to reach consensus. That caused a lot of (un)necessary conflicts. There's no such problem in a higher level civilization if the "ego" is quite different one then our "ego" from nature evolution of our current environment, then the democracy is not necessary or, maybe it's already implicitly exist.

This is a speculation on "Beyond Humans" upwards
