A decade from now Quantum computing will be in the same place it was a decade ago, on the cusp of proving a quantum advantage for tailor made problems in comparison to normal availability supercomputers. Classical compute will advance in that time period to keep the quantum computers always on the cusp.
The major non-compute related engineering breakthroughs needed for quantum computing to actually be advantageous in a way that would be revolutionary are themselves so revolutionary that the advancements of quantum computing would be vastly overshadowed. Again it's a case where those breakthroughs would so greatly enhance classic compute in terms of processing and reduction in costs that it still probably wouldn't be economically viable to produce general purpose quantum computers.
