Yes, I keep this in mind whenever a new alleged quantum breakthrough is being reported on. 

I now wonder if this kind of classical feats are more actively being researched _because_ of these quantum supremacy claims. Regardless, the end result is academic progress (at the least), so not gonna complain.

Using a conventional computer and cutting-edge mathematical tools and code, physicists at the Center for Computational Quantum Physics (CCQ) at the Simons Foundation’s 

 and collaborators at Boston University have cracked a daunting quantum physics problem previously claimed to be solvable only by quantum computers.

The technique is so groundbreaking in its efficiency that the researchers were even able to use a personal laptop to solve the problem.

Despite using only modest computational hardware, the researchers demonstrated that their simulations yielded state-of-the-art accuracies. The simulations converged on solutions that matched theoretical predictions and provided accurate results when applied to smaller test problems. The results also agreed with those reported by the quantum computing researchers — but with no quantum computer required.

Effectively they are using modified tensor neural-nets to approximate qubit like entities.

Whats most interesting here is that this keeps happening. QC makes claim of some novel usecase, classical computers then solve the problem using traditional computing tools....and in this case even a laptop can best a multi-billion dollar QC.
