I think transportation infrastructure is a great solution to yesterday's problems.<p>Look at the newspaper industry: some commentators think their problem is that delivering news on dead tree is overly expensive relative to what people want to pay for it.  Even if you accept that diagnosis, increasing investment into dead tree processing, dead tree distribution, and dead tree delivery is <i>not</i> the way forward.<p>I use trains to commute to my job as a computer programmer.  My commute is fairly inexpensive, hassle-free, and uses the best distribution system for human bodies the world has ever seen.  My commute is also a jaw-droppingly stupid waste of resources.<p>My company and I waste three hours a day five times a week shuttling a few pounds of grey matter and a pair of eyeballs from one glowing screen to another glowing screen.  The glowing screens connect to each other instantly, for so cheap next to my (cheap) train passes it doesn't even make sense to measure.
