In 1989 Marc Stiegler published a "fact" article in Analog science fiction magazine titled "Hypermedia and the Singularity." I have not been able to find a copy on the Web, but I recall that Stiegler in this essay anticipated something like the World Wide Web, and he predicted that the emergence of such a multiply cross-linked information system accessible to a few hundred million people would boost humans' effective intelligence and lead to a discontinuous jump in the ability to generate knowledge and solve problems.
Large swaths of the planet still aren't "wired," but at least ten percent of our species has had the Internet, if not the whole Web, at their disposal, some for over a decade now. Assuming you could quantify what Stiegler forecast, has anything of the sort happened? To me, our society still seems as cognitively dysfunctional as it was 20 years ago, and it's certainly not responding rationally to the prospect of Peak Oil, given all the information available about the increasingly distressed oil supply system. Where is the emergent super-intelligent collective behavior we're supposed to see by now?
