@The_Lagrangian actually the causal structure is perfectly well preserved (when seen from the inside)

@The_Lagrangian What if there isn't an inside when there's not an appropriate causal structure? That's my claim.

@The_Lagrangian thought experiment: take a machine with finite states, the computation is a path through these

@The_Lagrangian step 1: compute a few (or a lot) of these transitions
step 2: compute one

@The_Lagrangian now take [2] and one transition from [1] so that "[2], then [1]" is causally coherent

@The_Lagrangian all under the assumption that you somehow need to "physically realize" a computation

@The_Lagrangian this is shuffling the computation in outside causality while inner causality is preserved

@The_Lagrangian I don't get what this bit means. twitter.com/allgebrah/stat & maybe too simple to have an inside view

@The_Lagrangian "[2], then [1]" is a computation that could've happened, each of its steps has indeed happened

@The_Lagrangian If (1) is "run universe 12 steps from big bang" is "2 then 1" running 13 steps?

@The_Lagrangian if you find a [2] that could conceivably happen causally-before the bang, sure

@The_Lagrangian So I think in the first case (where we run (2) second) there's no casual connection with (1)
