Functionalism, consciousness, and experiencing qualia are radically different questions.

I believe it's possible in theory to simulate a human brain on silicon, and that this simulation would have something like consciousness and would experience qualia if somehow embedded.

I don't think that such a simulation would be ontologically or morally similar to an actual human.

You can call this spiritual if you want. But most people care more about humans than computers, even if the computers behave like humans.
