The article doesn't explain that "Quantum supremacy" is a term that means that the quantum machine can solve any single solution, no matter how contrived, faster than a conventional computer could in a reasonable amount of time. So it's a very important yet basic proof of concept for a quantum machine, and doesn't indicate how close it is to 1. solving useful problems, and 2. consumer accessibility.

Also, I was surprised there was no discussion of cryptography, which I thought was the most serious concern surrounding quantum computing.
