Digital minds have an off-switch, and digital have-nots could still have axes and guillotines.

But that's beside the point that encoding something has complex as a single human neural system requires several orders of magnitude more computing power than we've yet deployed in totality. Just the "parameters" of the human neural system would be in the 100s of trillions. A single neuron is more complex than most entire neural nets we've built.

We'd have a long way to go, and that's just assuming everything about consciousness and awareness is strictly mechanism.
