Agreed, but gambling is not my gig. I don't live that far from Las Vegas if I so prefer. I think smart contracts are interesting because I'm a programmer. Someone once wrote that Bitcoin also has executable code so that's on my list to investigate. It's something to do in retirement. I wish Elon Musk well, but he's only human, so I don't expect him to have investigated in depth every thing he talks about. He forms half-assed opinions just like the rest of us.
