Describing The Web With Physics 133
Fungii writes: "There is a fascinating article over on physicsweb.com about 'The physics of the Web.' It gets a little technical, but it is a really interesting subject, and is well worth a read." And if you missed it a few months ago, the IBM study describing "the bow tie theory" (and a surprisingly disconnected Web) makes a good companion piece. One odd note is the reseachers' claim that the Web contains "nearly a billion documents," when one search engine alone claims to index more than a third beyond that, but I guess new and duplicate documents will always make such figures suspect.

Vulnerability to Carefully Coordinated Attack? (Score:2, Interesting)
Consider this example, though it isn't meant to be analogous to the internet in any way. What if the President of the USA, the Vice President, the entire Cabinet, the entire Senate, the entire House of Representatives, etc. etc. were simultaneously assassinated? Can you even imagine ensuing chaos? You can even throw in all the state Governers, whatever, but that still wouldn't come out to more than the top 0.0004% of the country's population, in terms of "political importance" or some other metric. Is this scenario plausible or worth worrying about? You decide.

Advantage of Scale-Free Topology (Score:2, Interesting)
The problem with getting rid of the current Internet is that we would probably lose the advantage of having scale-free topology ... something the PhysicsWeb article discusses at length. Scale-free topology is one of the key factors in keeping the current Internet stable and relatively fault tolerant even as the number of users have grown exponentially. I doubt that those who want to replace an open Internet would create a replacement that would incorporate this type of scale-free topology.

complexity and deregulation (Score:3, Interesting)
THat's not to say that understanding how the various layers of complexity architecture and dynamics won't provide an answer ... and not because I think such diciplines suck, but because we have and will continue to have commercial influences on how networks are established.
Certainly some, in fact many businesses will higher and follow good practice. The problem comes about when some large companies don't. Or worse when mergers and buyouts occur, e.g. Verizon, CIHost and a few others come to mind.
Not to sound anti-business, because business has footed much of the bill for Internet expansion ... but rather to voice concern that sometimes there is a big disparity between technical solutions and the shareholder's bottom line.

Please don't take this the wrong way, but that's honestly the sort of question I'd expect from someone who doesn't understand computers.
While I believe in the possibility of machine intelligence (along with the moral, ethical, and most importantly philisophical questions that raises), the net is more of a data transfer mechanism than a processing mechanism. Short of very delibrate projects, such as SETI@Home, you just don't have your average machine on the net doing random computation. In that sense, the net really hasn't changed much since its inception. Further, if you did have a distributed consciousness, what would the consequences of lag, network outages, and outright crashes be? In that sense, it would be interesting to see if random/semi-random/genetic algorithms are capable of generating an intelligence capable of coping with such noise. However, I think such issues would rapidly kill off something before it became "evolved" enough to cope. If we do get an intelligence, I think it'll be something that happens on purpose. It may be distributed (maybe as a redundant, non-real-time simulation of a brain), but I doubt it'll be a spontaneous Skynet-like entity.
