If there's a lot of financial analysts and engineers saying "this isn't feasible" and they are being ignored then that's a bad reality distortion field.

Hyperloop One in particular comes to mind here. Some people say its feasible. Some say it isn't. Both have valid points.

I like his work. I just don't want to see Musk fail due to lack of focus on one particular part of the dream and a lack of people on his team willing to say no.

Unless he invested and I don't know about, Musk has nothing to do with any Hyperloop companies besides presenting the incomplete idea of a hyperloop and that it's worth pursuing.

Fortunately, Musk isn't involved too deeply with the Hyperloop bubble.
