I think a society must first define their values before trying to align to them.

Elimination of pain and suffering as a primary value, changes everything. A superintelligent overlord given that objective would simply eliminate all life on earth. If preservation of life was a value, it would sterilize everything and put all existing life in a coma. If the objective was happiness, it would drug us during the coma.

But it would not be so dumb as to choose those things. I don’t know what it would choose exactly, but, I think it would have something to do with the purpose of life itself in this universe, which can be seen as a fundamental force to fight entropy at the mesoscale between electromagnetism and gravity.
