Ice is the solid form of water.

Fire is the visual effect of a highly exothermic oxidation reaction.

You are comparing apples with black holes.

Brains run on neurons. Neurons run on Sodium and Potassium potentials which send electrical impulses to other neurons.

CPU have transistors, transistors run on action potentials generated through directed flow of electricity.

The only difference is one is carbon based the other silicon. Why does carbon allow conscious but silicon does not? If the fundamental actions are the same in both, their gestalt being the same or similar would follow.
