If I became a Power, I would upload the rest of humanity,
not murder you for your spare atoms. *I* am: <drum roll>
		SMART ENOUGH TO BE ETHICAL
So, presumably, are They.
The Powers will be more ethical than we are because:
1) They won't be distracted by morality.
	- Morality can be defined as the set of emotional reflexes
	given us by evolution to promote our inclusive fitness.
2) They'll be able to solve the hard problem of ethics.
	- What is the meaning of life?
3) Nothing will threaten Them.
	- In order to threaten Them, the offender would have to
	reach a point where ethical behavior is obvious and
	compelling.
Why wouldn't They upload us?
