But there’s no reason to think it isn’t.

That’s not the case. This is a very active area in academic philosophy and there are, objectively speaking, several reasons to think that consciousness is not solely a material process (whether or not you think these are good reasons is for you to decide). For an accessible introduction to this topic I recommend Facing up to the problem of consciousness by David Chalmers. The Stanford Encyclopedia of Philosophy entry on the Knowledge Argument is also a good intro if you are looking to dive right into something a bit more technical.
