If a system is conscious of an enormous number of things, like every frame in a film, but if each frame is clearly distinct, then we’d say conscious experience is highly differentiated.Both your brain and your hard drive are capable of containing such highly differentiated information.

There are many billions of cross links between individual inputs that far exceed any (current) computer.
