Not to be melodramatic or anything, but I would die without media - suffer greatly at the very least. The closest relationship that I have is with my iPhone. I regularly write sweet nothings in my "Notes" app for it. Not literally, but it knows how I feel.
I truly do think that if the world didn't have media, there would be complete anarchy. Things would be wildly misinterpreted; no "sorry I didn't make it to your poem reading last night, I have no phone to remind me" texts. Which wouldn't necessarily be a bad thing, missing that poem reading, but your friend would be super angry.
This becomes more substantial with the thought that world rulers could not converse with each other; how would we communicate what goods to export? We couldn't. So many problems arrising from this, and causing us to be "in our own world" even more than before. As if that were possible.
It is because of our reliance on media, getting the message across and all of the many other comforts it provides us with that this deprivation would be horrifying. We are USED to being babyfed all of this social information that shows up in people's profile descriptions, etc. that there is no need for handwritten letters or icebreakers anymore. Most people don't even know how badly they rely on their e-calendars, etc. and the shock that all of their stored information had all-of-a-sudden disappeared would petrify most.
You don't know what you've got 'til it's gone.
