You are assuming that there is no innate quality of human organic compounds and processes that differentiates us from electrical components. It may very well be the case that this is either true or false. We simply don't have enough evidence. It's true, we can't prove it one way or the other at the moment, but that usually just means that Occam's razor should guide our speculations and assumptions. Since the brain seems like all it's doing is performing some computations, why would we ever assume that its true function is to do something more than that? And given the fact that we are discovering new properties of matter and organic reactions all the time, there is a bias towards this being false. There's a good chance that the way the brain achieves its computations is indeed a bit more complex than, for instance, an artificial neural network, absolutely. But that's an implementation detail, and there's certainly no reason to assume that there's no computational model that can account for it - biologists are very close to having full working models of individual neurons already. Further, it's highly likely that the brain does its job in a biologically convenient way, not a logically convenient one, and I'd give good odds that there are a lot of logical simplifications that could be made to end up with a cleaner architecture that performs the exact same tasks.
