I'm absolutely fascinated by the difference in responses I see on HN versus talking to my friends (liberal arts). They were concerned with the future implications for cultural integrity as well as how it would effect labor forces and capitalism as a whole. Any thoughts?

I, for one, think this technology is awesome and think it could follow the progression that the train system went through in the US (transcontinental railroad, expanding, webbing out, lightrail, subways, trams, metros, etc) and see this as a possible next step in the evolution of transportation.
