With respects to the concept "artificial intelligence" (AI) there are some fuzzy edges, to say the least. What is intelligence? Is it defined by cultural parameters? Being "smart" is very likely to mean something completely different for a machine (AI) than for a man. I would say that it follows from this that a hypothetical alien life form which has a stucture and strategy for self maintenance that is vastly different from ours is likely to have a system of abstract cognition which is also vastly different from ours. Perhaps all meaningful communication is left a practical impossibility? I'd say that it's possible to visualise a type of intelligence which isn't about manipulating your surroundings ("nature") at all, but rather about accentuating the efficiency of adaptation. This will make the idea that you need to have as well "culture" as advanced technology in order to qualify as "intelligent" obsolete. In order to reach out for a common denominator: Is is fair to say that "intelligence" is about how you process information?
