this is vaguely related to the string theory related post from a day or two ago, it’s all bazinga science folks TL;DW string theory is a big thing because people that read pop science really liked it and it took a long time for physicists to come out in force and say “this is untestable garbage”
Among physicists, probably still something like Copenhagen. Most of them don’t really think about it too much.
I vaguely remember seeing a study that polled physicists and found that most of them supported copenhagen. It helps that the copenhagen interpretation is kind of the bare minimum you need to do quantum mechanics and the issues with it like what counts as a measurement never come up in practice: a measurement is whenever the physicist measures something.
