Exactly. This is a great description and may end up being the state of things forever. A precise definition likely requires that the thing being defined is significantly less complicated than the thing defining it. I suspect a proper physics definition of consciousness would necessitate singularity-quality general AI. But then you'd be unable to define the distinction between those consciousnesses and the more advanced one that was defining them.
