So is this actually useful for anything practical? Even with my limited understanding of the state of the art, I'm pretty sure that "factoring large numbers in milliseconds" is not actually something that D-Wave machines can do.

The nice thing that the uncertainty of what they do can be resolved now.

Im pretty sure d wave never claimed to be able to run Shor's algorithm either

To my knowledge, there are still no tasks a D-Wave is better at (asymptotically) than a classical machine

Last time I checked they haven't even beaten semi-recent laptops in direct comparisons of execution time, even for very synthetic problems.

For some time DWave hasn't been making their claims about their systems from the perspective of a black box, the contest has been more about whether we're seeing real quantum behavior inside the machine even through it doesn't appear to have a speed advantage at the scale they can produce right now. To do those experiments you need access to a real machine, so I don't see this resolving anything unless a user of this service comes up with a new problem for which there appears to be an asymptotic advantage.

The superposition of D-Wave's states has collapsed?
