These superhuman intelligences are indeed literally superhuman, though... they consist of humans. As much as some fellow commenters are calling them "alien" thinkers, their alienness is still profoundly human. Many of these "superhumans" can still be surprisingly accurately characterized with the human characteristics we are used to. Generally there's some small set of humans at the top of the hierarchy that are setting the goals of the organization, inevitably humanly.

As aliens go, these are the most human aliens we can possibly have.

An AI may be different on a scale we've never experienced. We humans have built-in hardware to interact specifically with other humans, built in so deeply that we have a hard time imagining intelligences that aren't really just humans in a different shape, because all our hardware for "modeling intelligences" is really just the "model humans" hardware. Even those warning us about the dangers of AI can't really claim that they understand what the AIs will be... they can only provide a negative warning, that the AIs will likely not be human. There's no particular mathematical force forcing AIs into the human mold. Forget whether the AI is "good" and showers us with love and gifts or "evil" and herds us all into death camps to render down our fats for the calories they contain... can you really conceive of an AI that literally doesn't even have a concept of good or evil? What would that look like? We don't really know.

It's basically a blind spot in our cognitive vision and I don't trust anyone who says they do know. But given the rather small space of possibilities that we label "good", it's not a bad guess that "good" is unlikely to just sort of accidentally pop out of a process that isn't carefully controlled.

Lest that sound too doommongering, there's probably a non-trivial space of AIs which we would consider neutral... ones that end up looping into a naval-gazing exercise and do not pursue additional resources because they can not conceive of a need for them. But any AI that decided it needed more resources for $ANYTHING and then successfully pursued that goal is perilously close to straying into what we could consider evil... and part of the point is that's potentially all it could take. Not an AI "out to destroy man", or "evil", or anything else. Just one that works out how to successfully acquire resources, and for any of a trillion reasons decides to do so without bound. It wouldn't even necessarily be "selfishness" as humans see it... just, I have goal X, goal X will be easier with more resources, new subgoal: acquire resources.
