In the interview, Koch continued: “certainly by any measure [the Internet is] a very, very complex system. Could it be conscious? In principle, yes it can.” And, pray, which principle would that be? I have started to note that a number of people prone to speculations at the border between science and science fiction, or between science and metaphysics, are quick to invoke the “in principle” argument. When pressed, though, they do not seem to be able to articulate exactly which principle they are referring to. Rather, it seems that the phrase is meant to indicate something along the lines of “I can’t think of a reason why not,” which at best is an argument from incredulity.
As it turns out, cosmologist Sean Carroll was the most reasonable of the bunch interviewed by Falk at Slate. As he put it: “There’s nothing stopping the Internet from having the computational capacity of a conscious brain, but that’s a long way from actually being conscious … Real brains have undergone millions of generations of natural selection to get where they are. I don’t see anything analogous that would be coaxing the Internet into consciousness. … I don’t think it’s at all likely.”
