Qubit? What's a qubit? What's a pair-wise coupled semiconducting flux qubit?
Since it unveiled its first working computer in 2007, the 72-employee Canadian company has faced skepticism from purists, who say the D-Wave system is a pale imitation whose circuitry doesn’t obey the laws of quantum physics. In its defence, D-Wave cites a 2011 paper in the reputable scientific journal Nature as proof that quantum properties are in play.
D-Wave Systems Inc. uses the relatively new adiabatic model, also known as quantum annealing. This architecture allows its quantum bits, or qubits, to shift from superposition to a traditional computer state.
Talking about ubiquitous quantum computers is like predicting that you'll drive a spaceship to work; it may revolutionize other things but quantum computing itself is not likely to be an everyday thing in our lifetimes.
If that's backing off, his original criticisms must have been blistering. He's basically saying in your link that there's no evidence that this is even a quantum computer; it may just be a classical device that happens to be a little faster than some others.
The sense I get from D-Wave is that they're trying to use the hardware startup model of research (which is a model, as opposed to Big Corporate and Big Academia) against the messy problem of Quantum Computing. Nobody actually knows if you can extract a useful number of qubits from the universe, but who knew the complexity limits of Silicon IC's back in the 50's or 60's? We'd probably have never found out if we had some other substrate that was already kicking ass.
