Also, consciousness is not binary (present or not), it is a gradient. I am more conscious than I was this morning when I groggily opened my eyes and hadn't yet fully booted up my model of the world. I am more conscious than my dog, which is more conscious than my goldfish, which is more conscious than a worm, etc. A dragonfly has consciousness, but only enough to model, "I am here. I want to eat that."
The scary bit about consciousness being a gradient is that we kind of consider ourselves the pinnacle of life forms mostly because of the complexity of our conscious experience. If consciousness is simply an emergent property of sufficiently complex information modelling, than assuming continued increases in computational capability, we're probably on the brink of creating consciousness that is "more conscious" than ourselves. And by our own definition of import, this consciousness will exceed our own place in the universe.
Will human life be the most important consideration in the universe if there is an artificial intelligence (actually, there will be nothing artificial about it) that is capable of modelling and empathizing with billions of life forms on an individual level?
