> Are you looking at a different world than me? I mean, yes? You seem to be focusing on what's happening today, whereas I was pretty deliberate in my framing of my idea as something "within the next century". And no, just because people are slow to adopt new technologies doesn't mean those new technologies never were developed. We have the technology today to connect every major city - and probably most minor cities - throughout the Americas or throughout Europe/Asia/Africa with high speed rail, and we probably have the resources, too. Hell, both were arguably true 50 years ago. Our reasons for not doing so are political, not technological.
