I'm a fan of the hyperloop concept and I hope it gets implemented. However, the Concorde example is useful to think about to me. Perhaps the reason we don't have better city-to-city transportation when there are options available and even implemented in other countries is actually that we lack the true will to build them.

This article does make the common mistake of suggesting the Hyerloop competes with intra-city subway systems though. I find the "just fix the subways" response to the Hyperloop disingenuous.
