We've currently never built a manned space ship for month long travels in outer space. We've never built a space ship that uses centrifugal force to simulate gravity and done longitudinal studies to verify that this doesn't have an adverse impact on Humans. SpaceX is has a market capitalization of 33.3 Billion. SpaceX which was founded 17 years ago has never had a manned flight. SpaceX has also never had a flight leave the atmosphere so far. But yes, it's entirely believable that they will go to Mars in our lifetime.

I can only assume he meant a manned flight.
