It is interesting, because some geneticists have speculated that we may be able to boost human intelligence to levels of 1000+. This seems impressive, but many big names out there are much more worried about an "intelligence explosion." I've posted about these type of things before, so no worries if this isn't a topic of interest.
Basically, this concern was first postulated by I.J. Good from what I can tell:http://en.wikipedia.org/wiki/I._J._Good
I don't remember who he was from the movie (Imitiation Game), but I guess he became very concerned with this concept:
"Let an ultraintelligent machine be defined as a machine that can far surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an 'intelligence explosion,' and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make."
Basically, the idea is that a machine could easily "go viral" in their abilitiy to increase intelligence leaving even a 1,000 IQ human far behind...
