OK. Complexity science is still young. > > You could tell me: "why do you think that we couldn't find a similar > sort of explanation for why God's activity is relevant to > consciousness".

So are you saying that the MGA doesn't show that COMP is incompatible with SUP-PHYS?

But what I actually said was it wasn't a priori absurd that a recording could be consciousness. The MGA depended on that absurdity at some point. I didn't say that recordings could be conscious. There is a difference. I appreciate your recent comment about doevtailing on too many conversations. Excuse my massive pruning of the conversation to assist in that direction!
