Agreed, and adding: Hyperloop wasn't original to Musk (other than name). RAND explored the concept in the 1970s, and there are further earlier concepts:
Look up Robert M. Salter at RAND:
"The Very High Speed Transit System" (August, 1972)
"Trans-Planetary Subway Systems -- A Burgeoning Capability" (February, 1978)
Going to Mars isn't a new concept, either. There are probably a thousand scifi stories about such.
But Musk is the first to take action.
