No, quantum supremacy is about quantum computers being better at one thing. Then there will be a reason to use them. It's like making a screwdriver when you already have a hammer. Sometime a hammer and nails is better and sometimes a screwdriver and screws is better. It's about picking the right tools for the job.

It isn't about them being better in the sense of faster than a classical computer, but rather scaling. Quantum computing is attractive because we expect that some operations scale much better with size on one compared to classical computing. ie if for a task the quantum algorithm is O(n) while the classical version is O(n!)
