I wrote about the interpretation usually used in published papers, and obviously decoherence alone does not solve the measurement problem as it only shuffles it to the bigger system, you need many worlds / Copenhagen / etc.

I don't bother watching youtube videos of what someone thinks quantum mechanics is about.

You don't have to watch a video. My first reference is to a paper.

Many worlds is just a way of describing the results of entanglement. It doesn't add any structure or dynamics to the wave function. Those worlds are precisely those slices the parent is talking about.
