If you start from the assumption that Musk is awesome then you probably won't like the article. If you read the article you will likely come to the conclusion that Hyperloop is half-baked and the proposal includes "detail" that is little more than flim-flam.

My problem with Hyperloop is that it's trying to solve the wrong problem. In less than twenty years the transportation landscape is going to be very different. The younger generation is not wedded to cars the way the last several generations were, and new transportation methods, such as self-driving vehicles are emerging. Assuming any kind of sane public policy, energy is going to get more expensive, speed of travel is going to become less of a concern, and connectivity will go through the roof. Why will I care about a fast tube for going from LA to SF? Whay's so great about fast? An inconvenient method for traveling really fast that doesn't let me chat or work might be far less desireable than a convenient method that is slow but doesn't disrupt my day.
