There's no way to tell if it does or not. And things start to get really weird if we grant them that. Because if we accept that not only nonhumans, but also non-biologicals can have a subjective inner experience, then where does it end?

And we still have no idea what exactly grants the inner conscious experience. What actually allows me to feel? I don't think it's a matter of processing power. We've had machines capable of processing faster than we can think for a long time, but to question if those were conscious would be silly.

For example, if you want to be a 100% materialist, ok, so happiness is the dopamine and serotonin reacting in my brain. But those chemical reactions only make sense in the context that I can feel them. So what actually let's me feel them?
