Some interesting science results, but essentially nothing in the way of economically-valuable computations. I think we'll eventually get there in the next decade or so, but even before that, there are immediately useful spinoff technologies coming out of the effort like quantum sensors and greatly improved RF and photonics products. Even if/when these things are working on a useful scale, quantum computing is going to be more comparable to special-purpose accelerators like GPUs, or perhaps akin having a re-programmable physics lab-on-a-chip. It will be advantageous for the subset of problems that can be cast in the form of Schrodinger's equation, of which there are many. For example, you can use the quantum computer to generate high-fidelity solutions of the electronic structure of some classically intractable molecule, and use those solutions as the training set for a classical AI model that then goes and performs the bulk of the computation on whatever it was you were trying to do.
