How does collapsing of the wave function correlate to any of the interpretations of quantum mechanics?
Isn't it that to measure a quantum object, we have to interact with it? Doesn't interacting with anything change how it works? How is it special in this case?
How does that relate to MWI or Copenhagen for example? What does any of this mean in the macro level?

I'm trying to understand the significance of this thing, and why there is still debate over it
