It is crazy that. For time immemorial we used to transmit information from our mouths or using hand signals, and receive that information through eyes and ears, all in realtime.

(side thought: how awesome would it be if we had a single organ for both? e.g. communication solely through blinking)

Then suddenly we have this system where someone can code meaning onto a sheet, and we can receive entire contexts from a glance alone, purely at our leisure. Nuts.
