Now discuss whether a bonobo, a dog, a cat, a mouse, an ant, a bacterium is conscious.

And you’ll find it’s not as clear cut.

I'm pretty sure the mammals are conscious the same way I am, in that they experience qualia the same way I do. Insects and bacteria, I suspect not, but how could I tell?

There is no way to prove that other humans experience consciousness, really.
