Grigori Perelman was that reclusive Russian mathematician who proved the Poincaré conjecture, and refused the $1,000,000 prize. He has reportedly said that he refused the reward because he knows "how to control the universe" (full quote below; article linked at end).
When asked why he refused from the prize of one million dollars, Perelman responded: "I know how to control the Universe. Why would I run to get a million, tell me?"
My immediate thought is that he refers to the fact that understanding of the world means control of the world, to the extent of your understanding and limit of possibility. Thus the saying "knowledge is power" (which, oddly, the public doesn't really think seems to apply to science). I also see the point of refusing to communicate with the media, which manifestly does not care about science but rather about celebrity (I'm not guilty! this post is just about his ideas, dammit!). But his other comments - about the "boundless", for instance - sound more wild-eyed and vague, so maybe he's thinking of something else.
Also, what is this nonsense at the end? I think it's probably a misinterpretation by a reporter. Or wild exaggerations by Perelman. Or are we all doomed to be folded?
The scientist has learned some super-knowledge which helps realize creation. Special services need to know whether Perelman and his knowledge may pose a threat to humanity. With his knowledge he can fold the Universe into a spot and then unfold it again. Will mankind survive after this fantastic process? Do we need to control the Universe at all?

Sure, we can take that for granted seeing how we're not floating superbrains (yet) :D
Efficient to have some intelligent people? Efficient for whom?
Either this is a missunderstanding on my part, or alternatively I would recomment (re?)reading "The Selfish Gene". Because if the answer to who it is efficient for isn't "really, really close kin" I can't think of anything else that could be a valid answer. And how did the reproductive success of brothers and sisters benefit from having a highly intelligent nerd as a sibling?
EDIT: Actually I can think of another answer now that seems more plausible than the kin idea involving an evolutionarily stable strategy. But thinking it through that sounds quite implausible as well.
If we are talking about the evolutionary advantages of intelligence we are almost exclusively talking about the advantages that intelligence could possibly have for the reproductive success of the individual, not the society or the group (s)he's a part of.
The kind of intelligence that was probably most heavily selected for is social intelligence, aka. understanding, navigating and manipulating social relationships. The kind of nerd intelligence you witness in Perelman and around here seems to be an evolutionary by-product of that at best, because let's face it - highly intelligent nerds are weird outliers and rarely seem to posess high attractiveness to the opposite gender in a way that would be able to make their genes outcompete other spunk floating around in the gene-pool. That's why nerds didn't take over the gene-pool in the past, which is why we're still so stupid and overly concerned with all the "wrong" things.
In other words, if we're talking about the evolution of human intelligence, I think we're talking about a very narrow set of (mainly social) intelligence that evolved by being directly selected for, while general intelligence skills like mathematical prowess and rationality are more of a by-product that weren't ever directly selected for. (If anything I'd guess they were rather selected against).
In this vein, I often observe that our entire technological civilization was a side-effect of the human urge to gossip.
