without some kind of interactive growth or training? How can
‘brute-force resurrection’ create something human-level or greater
*that once existed* ‘from scratch’ without also simulating all the
environmental input factors that conditioned that being?

Even if there are only x^y states of ‘matter’ possible and infinite
computational resources at Omega could compute all possible
combinations, how could ‘The System’ ever *select* those
configurations that might have had some resemblance to actual history
