I give him that much credit because if he was wrong, it would be easy to demonstrate. Give this computer an instance of a problem, show it performs much better than the best conventional computer. If this bar is met, there's only so much obfuscation that can be thrown up, if this bar is not met, there's only so much obfuscation that can be thrown up. So far it seems the bar has not been met.

Scott Aaronson has agreed that they've reached a new high, which also helps his credibility in my mind. But they have not reached what they claim they've reached. And being able to solve only one highly restricted problem is a long way away from having a quantum computer. Basically, if you look at what D-Wave actually has, it's a great deal less impressive than their marketing would like you to believe.
