Quite interesting paper.

Interpretation remains difficult, but as far as I grasp it, it support the 0 world but many points-of-view/"dreams” interpretation of (universal) truth.

The problem of the “many-world” is that a “world” is not an easy concept that we could take for granted. Relative state is better, but sum on histories can be even better. The difficulty (when we assume mechanism) is in justifying the linearity at the bottom for the "measure one” of the observable. It has become a mathematical problem, just to see if the arithmetical observable (which are well defined through the logics of self-reference) are linear enough.
