Indeed if I had millions/billions to invest I'd rather throw it at Elon. Not only would I have a reasonable level of expectation of seeing an ROI, however long it might take, but also I could expect to see social return. Something that truly moves the human race forward. There are tons of teams that could make Instagram, Groupon, OMGPOP or Pinterest, etc. Very few that could do SpaceX. Bet on talent. Especially rarer talent with a track record.
