Is that really the case though? An observation collapses a wave function. The Copenhagen interpretation suggests that the collapsed state arises from a probability distribution, but it does not address the "fundamental" origin of that distribution. MW attempts to address it by suggesting that the rest of the reality just went elsewhere, rather than disappearing or never having existed at all, but it still does not explain why "we" get "this" reality. Both rely on observations to collapse the wave function, and neither specifically calls out a conscious agent as necessary for an observation to occur. Observation is a measurement, whether intended and registered by a brain or not.

Not if the MWI is true. Talking about wave function collapse presupposes that the Copenhagen interpretation is true. In the MWI, there is no collapse; it's unitary evolution all the time.
