Thanks for recommending.

Suffice it to say that you are wrong, and power does not bring with it morality.

I have never assumed that "power brings with it morality" if we with power mean limited power. Some superhuman AI might very well be more immoral than humans are. I think unlimited power would bring with it morality. If you have access to every single particle in the universe and can put it wherever you want, and thus create whatever is theoretically possible for an almighty being to create, you will know how to fill all of spacetime with the largest possible amount of happiness. And you will do that, since you will be intelligent enough to understand that that's what gives you the most happiness. (And, needless to say, you will also find a way to be the one to experience all that happiness.) Given hedonistic utilitarianism, this is the best thing that could happen, no matter who got the unlimited power and what was initially the moral standards of that person. If you don't think hedonistic utilitarianism (or hedonism) is moral, it's understandable that you think a world filled with the maximum amount of happiness might not be a moral outcome, especially if achieving that goal took killing lots of people against their will, for example. But that alone doesn't prove I'm wrong. Much of what humans think to be very wrong is not in all circumstances wrong. To prove me wrong, you have to either prove hedonism and hedonistic utilitarianism wrong first, or prove that a being with unlimited power wouldn't understand that it would be best for him to fill the universe with as much happiness as possible and experience all that happiness.

a happy person doesn't hate.
