Oh, I'm a Musk fan and find him to be impressive. I'm just specifically skeptical of the hyperloop, not necessarily tunneling innovations. If he can indeed tunnel cheaply, it makes lots of stuff cheaper. I still don't understand how the hyperloop would be cheaper than trains, though. I think generally his insights prove to be pretty easy to understand, once he's communicated them. Except for the hyperloop, which sounds interesting and plausible, but still seems half-baked years later. And if you're going anywhere closer than Milwaukee, the benefit of a speed of sound travel capsule faces rapidly diminishing value.
