About your first point, "outpaces current supercomputers, solving tasks in minutes that would otherwise take billions of years.", that is the point of the article. They used their computer to model a system that can't be verified with a classic computer algorithm, so no, we are not certain that it is solving anything. About the other points, quantum computers are massively different from classic ones, so much that there are very few algorithms for them. For example, GPUs are faster at matrix multiplication because it can be implemented independent parallel threads, but they suck at other problemas. A quantum computer is good for running quantum algorithms [1], of which there are very few at the moment, and most of them are useful for simulating quantum physics. It is not a "faster" classic computer in any way. https://en.wikipedia.org/wiki/Quantum_algorithm https://en.wikipedia.org/wiki/Quantum_algorithm
