For example, maybe they figured out how to convince it to accept some threshold of certainty (so it doesn't eat the universe to prove that it produced exactly 1,000,000 paperclips), it achieved its terminal goal with a tiny amount of energy (less than one star's worth), and halted.
For a moment lets assume there is some alien intelligent life on our galaxy which is older than us and that it have succeeded in creating super-intelligent self-modifying AI.
Then what set of values and/or goals it is plausible for it to have, given our current observations (I.e. that there is no evidence of it`s existence)?
Some examples:
It values non-interference with nature (some kind of hippie AI)
It values camouflage/stealth for it own defense/security purposes.
It just cares about exterminating their creators and nothing else.
