There are quite a few people that actively do research and debate on QM foundations, and, among that group, there's honestly no preferred interpretation. People are even looking for alternatives that bypass the problem entirely (e.g. GRW. The debate is fully open, at the moment.

Outside of this specific field, yes, it's pretty much shut-up-and-calculate.
