Alien AI is using SETI-attack strategy, but to convince us to bite and also to be sure that we have very strong computers which are able to run its code, it makes its signal very subtle and complex, so it is not easy to find. We didn't find it yet but will soon find. I wrote about SETI attack here: http://lesswrong.com/lw/gzv/risks_of_downloading_alien_ai_via_seti_search/
Alien AI exist in form of alien nanobots everywhere (including my room and body), but they do not interact with us and try to hide from microscopy.
They are berserk and will be triggered to kill us if we reach unknown threshold, most likely creation of AI or nanotech.
2 may include 3.
This looks far fetched, but interesting strategy. Does it perhaps ever occur in nature? I.e. do any predators wait for their prey to become stronger/smarter, before luring them into the trap?
I guess they could, but to what end?
Why wait?
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.
Other thoughts?
