It remains to be demonstrated that D-Wave has an asymptotic advantage over classical optimization algorithms. Even synthetic spin glass benchmarks specifically designed to give the DW an advantage show no advantage.

Furthermore, real optimization problems have high connectivity, high weight cost function terms, and require higher precision than available. The first two will require an unacceptable overhead for fixed topology solvers. DW is not useful for real world optimization problems.

Google on the other hand has actually done something a classical computer can not do
