Shock-level-bragging is so 2003… ;) Still, in my opinion, this post contains some extremely interesting unconventional intuition, which seems to be way underrated.
In the long run, this whole mathematical multiverse idea has the potential to become much less insubstantial than it may look on superficial inspection.
There are quite a few problems with it though. For example the reliance on minimum description length does not feel like the right approach to the probability problem at that level. It may turn out to be eventually, but generally, the perceived probabilities don’t come from a conscious decision to care about some abstract (and uncomputable!) complexity measure (like MDL)
No! We experience certain probabilities, because something is built into the very nature of our physics (or rather meta- or multi-physics). So, even if MDL turns out to be at the core, it must be a derived consequence, rather than just being pulled out of the hat as in the OP.
The most essential clue in the puzzle could be, if we’d manage to understand how this glue works that connects processes with phenomenologically equivalent or similar information processing structures. I can see Barbour’s derivation of the general relativity as an interesting analogy. But it’s obviously much harder to argue about general (approximate) isomorphisms of causality networks than measuring the similarity of mass distributions of three dimensional spaces.
Nevertheless I think the intuition multiverse ideas provide could inspire speculations in extremely exciting directions: For example: Is it conceivable that the symmetries we experience in the physical laws are plainly consequences of the natural symmetries of this observer-gluing process itself?
Due to anthropic reasoning it is impossible to understand unless you have heard about shock level 8, you will never find yourself in a universe where you hear about shock level 8.

Just wait until you hear about shock level 7.
Q: How do you convince a singularitarian to eat shit?
A: Declare eating shit shock level 5
Due to anthropic reasoning it is impossible to understand unless you have heard about shock level 8, you will never find yourself in a universe where you hear about shock level 8.
It’s 4chan.
