No magic is necessary to understand that carbon & silicon are not equivalent. The burden of proof is on those who think silicon can be a substitute for carbon & all that it entails. I don't buy into magical thinking like Turing machines being physically realizable b/c I have studied enough math & computer science to not be confused by abstractions & their physical realizations.
The proof immediately follows from the ability of silicon systems in principle to model carbon ones with arbitrary precision.
I recently wrote a simulation of water molecules & got really confused when the keyboard started getting water condensation on it. I concluded that simulating water was equivalent to manifesting it in reality & immediately stopped the simulation b/c I didn't want to short-circuit the CPU.
