Been mulling these ideas more since yesterday.
Big on my mind is the physical/digital divide. Digital things have some physical existence. They are encoded in circuits or on hard drives and disks. However, our minds can't grasp those things unless they are mediated through a computer screen or are projected into the physical world in some other way.
We grasp physical things through a single medium, that of the senses. We grasp digital things through two mediums: the computer and screen, and then the senses. This digital goods are further abstracted from the reality our mind can grasp.
