Somebody then had the audacity to pester him with Hyperloop on the earnings call for Tesla. It's like asking the president about his veggie garden while hes giving a press conference on the war on (whistleblowers|drugs|terror).
No air, no water, no plants or animals, no fuel, plenty of radiation (on the trip and while there) and dust and extreme cold. Other than very expensive chest-beating (for which the Moon is a closer dead body), reason suggests that continued support of robotic exploration will pay off better for science.
In the meantime we can invent new technologies which will greatly ease the burdens and dangers - once we have invented actual goals to make of such journeys worth the enormous investment.
Long-distance tube transport seems more than a little pipe-dreamish. Regional OTOH seems inevitable.
With Tesla, on the other hand, I'm with you. I see Tesla like Luciano Pavarotti back in the day. Arguable the greatest in his field, but no matter how amazing he was, he did not end up changing everything we know about music. He started the huge change on how general public sees the opera, but he wasn't alone and it was just the beginning.
Now, Tesla might be the beginning of a big shift towards how we perceive electric cars, and it could even be the next Ford or General Motors, but it's not the next Benz Autowagen or the invention of the railroad, which Hyperloop clearly would have potential for.
