  1. It seems to me that the wave collapse on measurement is such a huge sudden change in the system that it doesn't make sense. I've yet to understand why Pilot wave theory is not assumed to be the more accurate description of the universe. I do understand that Copenhagen interpretation and wave function collapse are mathematically easier to handle than Pilot wave theory – in the same way as Newtonian physics are easier to understand than the general relativity. Pilot wave theory explains the same real world measurements without a need for sudden collapse of the system on measurement and without a need for parallel worlds interpretation (many worlds theory). My guess is that Pilot wave theory is closer to reality but many worlds theory may still be usable because it results in the same predictions for all practical experiements and the mathematics are much easier to handle. Thatmakes many worlds theory the metaphysical truth: not exactly the real truth but pretending that the world behaves according to that description still results in practically flawless results.

  3.  @20firebird  I think the cat is an important part of the thought experiment because it's used to extend the dynamics from the single atom to macroscale. As a result, the cat observing its own state is a huge problem for the experiment.
