Whether or not you agree that D-wave has proper superposition and is properly performing quantum annealing your original statement was different from this one. You wrote: "it can test the superposition of the entire search space instead of picking at points here and there." That's similar to common misconceptions on how quantum computers work which might attract some of your downvotes, but more importantly you're also misrepresenting why quantum annealing is faster than thermal annealing.
