I feel like a true meritocracy would be a system kind of like Plato’s republic where children are separated from their parents as early as possible and are all raised from the exact same level, so the only thing that sets them apart will be individual talent (their merit). If not this, then the wealth, status and connections of your family will influence your opportunities, which runs counter to meritocracy.

Safe to say it’s not a system I’d want to live in.

Omnipotence without knowing how to control it could very easily instantly annihilate you, whether physically or mentally through complete ego death.

this is exactly why the kibibyte, mebibyte, etc. were introduced.

Anything good?

Then all of them. They are human beings, not black holes of pure evil.
