or you mean specifically the parallel computation view?
Unsure about those working on quantum foundations, but I think the absence of consensus is enough to claim any view as absolutely not the view.
i think if you were to ask people to make a real metaphysical speculation, majority might be partial to everett - especially if they felt confident the results were anonymous
I believe the vast majority of researchers in quantum computing* spend almost no time on metaphysical speculation,
*Well, those on the "practical side" that thinks about algorithms and engineering quantum systems like the Google Quantum AI team and others. Not the computer science theorists knee-deep in quantum computational complexity proofs nor physics theorists working on foundations of quantum mechanics. But these last two categories are outnumbered by the "practical" side.
