I didn't have time to look into what happens in Hash Life in more detail.
For one the entire spacetime trajectory is contained in the hash, encoded.
For other, assembling a full trajectory frame and especially subsequent
trajectory frames is where the experience occurs.

As I said, I don't have time to think, so these are just opinions devoid of fact .
