Doesn't have to be "unchecked", just much less checked than human brains. Although, that is an interesting question in and of itself. Are living brains near a local optimum in terms of computing power, given heat and power constraints? With Moore's Law, the prediction was that computer intelligence would surpass human intelligence in a few more doublings. But now that the primary constraint is more about power usage than absolute clock speed, maybe living brains compare better?
