I feel like philosophers have an over-active desire to simplify. In their mind consciousness must be something elegant and having refined gem-like qualities.

As we see now, consciousness is probably a lot more fuzzy than we had predicted. We now have robot appendages for amputees that interface more and more closely with the natural brain. Even from this cyborg point of view, the patients don't seem to think so much about it other than simply "OMG, thank you".

The question of where "soul" exists is older than science, and not really something I could add anything to.
