That's not the point. You know exactly how to define being conscious and aware- it's your subjective experiencing of the world and of your inner states. The problem is that being a subjective experiencing, there is no way to communicate it to the outside world.
That's obviously incorrect, as humans routinely talk about their subjective experiences.
Maybe that's not as common with HN folks, but most other humans do.
