But we, humans, aren't going at anything like the speed of light. What if we tweaked our DNA to produce human beings with the working memory capacity of 50 items instead of the normal 7-ish [1]? One such researcher would be able to work faster, on more problems at once, and to consider more evidence and facts. The next bottleneck for that person, of course, would be the input/output capacity (reading, writing, typing, communicating), but even with those limitations, I bet they would be a lot more efficient than the average "normal" human. The question is - would you call such a person more "intelligent"?

Or we get more humans and then it's a coordination problem right? I mean there is a point in comparing individual vs collective intelligence. This is a bit like communist systems. They work in theory because you get to plan the economy centrally, but in fact more chaotic systems (unplanned) do better (check growth of capitalist countries vs communist ones).
