I think they are wrong in this case.

The guy doesn't stop talking about gold, and nobody says bitcoins are going to compete directly with gold or even other fiat money. Bitcoin will be successful ONLY just by taking away a part of paypal's and Visa markets. Those are their competitors and only with that its future is guaranteed as an exchange medium for some type of transactions. That might help stabilizing its price and allowing it use as the "digital poor's man value keeper".
