Let me see if I understand how you construct the correct physics from
comp.

You start with the principle of the Universal Dovetailer, which creates
all possible universes. You then examine those universes for subsystems
which are consistent with your own first-person conscious experiences.
You set up some kind of measure over this selected subset of universes.
(The Universal Dovetailer perhaps implies the Universal Distribution.)
And based on this measure you arrive at first-person indeterminacy about
which laws of physics hold for you.

Is that right, is that the mechanical procedure by which someone derives
their laws of physics from comp?
