@Jeruba I understand that, but that logic also means that is is a mistake for many of us to even have a job, or at least to rely on being employed. See, if something happened to wipe out the electrical grid, my job (and that of many others) would be utterly impossible.—Try running a milling machine without power!—- Yet, I think we both know how vulnerable the electrical system is; I definitely learned that as I was freezing in the dark without water for a week in NH a few winters ago.
Like it or not though, our economy is no longer an agricultural or manufacturing one; it is one of information. Now, we can handle and overcome the technical weaknesses of that. In fact, that is the point of a decentralized mesh network. The issue we seem to have a hard time with is establishing a decentralized network that is resilient and virtually uncrashable since there are economic and political entities that wish to retain power and continue to profit.
Part of it is also that many people take for granted that we have always had the ability to share information globally and don’t remember a time when there were not cheap, fast computers with mice and color screens. It is beyond their imagination that such a world could ever have existed. We will forget for the moment that such a world still exists in most places on 2012 planet Earth. That makes it hard to gain momentum as there are relatively few people who understand how easy it would be for the world to return to a time when you had to wait for weeks for the Pony Express to relay information across the country. They seem to think that it is impossible that such a thing could ever happen, and doubly impossible that our own government would to that to us.
Many more knowledgeable and tech-savvy people like myself, Cory Doctorow, Jimmy Wales, and a crapload of others really want (and are working hard towards) a replacement to the Internet that is impervious to government/corporate control, and that doesn’t even really rely on electricity. Note also that the OLPC XO-1 (the one we give to poor kids in Africa) already has mobile ad-hoc networking, and can be recharged by a hand-crank. That means that, given proper motivation, we could have this done next week. We have the technology; we just don’t have the motivation to implement it.
Of course, if recent events are any clue, our real mistake is relying on governments and corporations; a centralized infrastructure unto themselves. We rely on the MPAA to entertain us. We rely on government to act in the best interests and according to the wishes of those who put them into power. We relied on big banks to remain honest in their pursuit of profit and put the majority of our money in a few institutions.
But you are correct that we are a nation of reliance. Look at how we rely on cheap oil. Look at how we forgot the lessons of the 1970s on that one and still ridicule the idea of alternatives like electric vehicles or mass transit.
