Well, if you're going to involve AI, then the entire 'government' paradigm changes. Honestly, under the guidance of any half-competent AI managing resources, distribution, etc...you reach Post Scarcity or Singularity pretty damn fast.
Past that point? It's questionable if government as an institution is even viable beyond 'giving people something to do so they can feel important and involved.'
Are you trying to suggest this is a bad thing? Less involved a government needs to be in society the better off you are. On a lower scale, the sign of a good society would but that police have
less work to do, not more.
On the note of Democracy being 'inherently' better than any other system of government, I'll have to disagree. Democracy has a lot of problems and I'll be the first to admit that other systems (even and especially monarchies and feudal systems) have their own problems as well. No government is any more 'optimal' than any other.
I'm not sure how you could believe this unless you've just ignored history entirely.
Humans are flawed creatures. The more power you concentrate in a human the more these flaws are magnified through their behavior. The more a government does this the more inferior it is.
Parahumans are even more flawed. They're people that in normal cases have extreme psychological damage and have giant alien space whales plugged into their brains that promotes more extreme attitudes and guides them towards conflict. Conflict is the last thing society needs.
If you'd read my earlier post, though, my point was to give parahumans largely ceremonial 'noble' titles that don't really give them much functional power. In my idealized version, such a governmental construct would center around a parliamentary system where the House of Lords (to use Britain's example) would be replaced by a House Of Parahumans, and the House of Commons would be the House of Citizens (or something). Functionally, it would very much be some manner of representative government ruled 'by the people,' but offer a different route of representation and different rules for governing parahumans, because they *need* a different set of rules.
Parahumans only need a different set of rules if the government is incapable of imposing the same set of rules on them as everyone else.
Giving them titles like this is nothing more than undeserved appeasement. Parahumans who use their power to contribute to society should be appropriately rewarded just as any human is.
Elevating someone's status by default because they have superpowers granted by a race that wants to foster conflict and eventually destroy humanity is sending entirely the wrong message. This is only something you would need to do if you were incapable of doing otherwise. Pantheon seems to be on a path that would not require such appeasement in society which is why I don't consider it.
Parahumans and humans are inherently unequal. To treat them as such under the auspices of either the law or government is...well, not going to work. This way, parahumans get to be told they're 'special and important' while not having too much actual power to fuck with the system, because as you said, Spacewhales are in their brains.
Parahumans and humans are inherently unequal, but not in a way that makes parahumans better at running a government. Their tendancy towards conflict in fact makes them
worse at it if their extremes are not mitigated by other checks on their power.
This is why democracy is important. Spreading around power and then using checks and balances to mitigate failings results in less problems overall.
This is why having AI involved in government (not that I'm suggesting they entirely take over government) is important. AI do not have many of the flaws humans do. Having this aspect contribute to government is a very, very valuable thing.
All in all, it seems like your view of what kind of government would come about is one that is too weak to institute a proper democratic government, instead being forced to kowtow to parahumans with fancy titles to appease their undeserved sensibilities of importance.
