Unsurprisingly, most of the people here haven't read, or perhaps not really absorbed, what TFA discusses, and are jumping to quick and irrelevant conclusions.
The author explains that Survival is a good metric of Intelligence, and he uses humans as an example. One human can definitely kill one lion, bear, mosquito, single bacteria, etc. if equipped with his intelligently designed tools such as a gun, or a mosquito zapper, antibacterial soap. He uses these tools, intelligently, to kill one bear, and hence, the human is more intelligent. However, if you take 10 bears, then sure, they may be able to kill the 1 human, but that means they are less intelligent, and take more numbers.
He simulates intelligence this way, and he defines a simulation as any environment with applied constraints, and that may include the internet, legal system, your neighbourhood community, etc.
So here's what he says: A system, such as the health care or legal system, will not be shutdown by one person. In fact, it probably won't even be shutdown by 10 people, maybe 100. And hence, the system is vastly more intelligent than a human, intrinsically since we worked in numbers to evolve this system.
I think it's a very interesting way of looking at intelligence. Again, this is all based Mr. Barbalet's assumptions.
