For us to envision that nightmare scenario is to presage the collapse of society, if collapse is defined at the exponential increase of inconvenience. Ironically, it is our search for convenience that will get us there. To get places faster, to do things easier, and all of it with ever increasing simplicity and ease is the hallmark of technological progress, but comes at the cost of ecological destruction and the ever increasing delegation of inconvenience to a growing underclass.
The problem is that if everything becomes convenient, convenience is lost. And it won't be because of expanding technology, but expanding numbers of people. That's because exponential convenience require more people to turn down our beds, pick our strawberries, and mow our lawns. Like a Ponzi scheme, to get to our exalted level of convenience, we need to make inconvenient the lives of an underclass of folks who will do all the grunt work. Indeed, if we didn't have a growing underclass to do all the work and all the make work, society would 'collapse', which is another way of saying that life would be relatively more inconvenient when faced the prospect of mowing our own lawns and making our own beds.
But underclasses have a way of moving up the the economic chain, thus demanding an even larger underclass to pick vegetables, wash our cars, and mind the kids. So with a surge in immigrant labor, the population explodes, and as berry pickers migrate up the economic ladder to become SUV pickers, we need a larger and larger underclass to support the pyramid. There is invariably a limit to this, when all the traffic stops.
But do we need to go that far? Collapse occurs when a society consumes its own seed corn by over population that results in depletion of its natural resources, with the result that everybody dies, or worse, eats each other. This sort of thing happened on Easter Island and with Mezo-American Indians. It is unlikely of course that society will ever develop a taste for soylent green (IT'S PEOPLE!), but there is another solution.
Ultimately, if the law of social dynamics means the price of convenience is the exhaust plume of a lot of inconvenience shunted to someone else, it makes sense that that someone else is in Never Never land. Take up space on a road and invariably you will block someone in the passing lane, but if you're virtually on the road, you can widen the highway with an eye blink, or with a press of the A button on your keypad, blow the traffic ahead to bits. Make convenience virtual and you take your ease entirely in your mind's eye. Thus as the world teams with people abutting each other cheek by jowl, our homes will become Nintendo-ized, and we will abandon ourselves to limitless virtual pleasures, including no doubt many empty roads.
