Well ... no. We have several interpretations of QM, one of which has been dominant for most of the last century. But the other interpretations have been getting deeper looks due to things that the current interpretation "hand waves" (particle wave duality, etc.)

We are generally willing to accept the interpretation, as long as we don't look to closely at it. Once we do, we have to start asking questions of nature as to which (set of) interpretation(s) are more likely correct. As in provides an understandable model, and provides correct calculation capability for predicting features given experiments.

That’s as silly as saying “we already have particle colliders, at this point they’re just an engineering problem”. It completely misses the forest for the trees.

Yes, quantum computing is not a problem in modern fundamental physics. Yes, collider construction is not a problem in modern fundamental physics.
