What do you mean by “Are we all just . . .”?
“Just”, as opposed to what?
It reads to me like you’re asking “are we doing anything else in life?” to which the answer is definitely “no, we are doing quite a few other things.”
I’m trying to imagine what else you might mean . . . you mention “media” and “Zuckface” . . . again, while much (or even, most) commercial media is trying to manipulate us to buy corporate (crap er . . .) products, even Zuckface and media have some other elements to them.
But maybe “just” was just a word tossed in there, and you really meant something more like, “Is media almost all produced with the intention of selling stuff?” then ”almost all, at some level or another, yes, though you can avoid it, for instance by logging into your free Fluther account so you don’t see ads, unless you count that you’re creating “content” which may draw other people who may see an ad. But there are still many other aspects of the activity which aren’t at all about commercial stuff”.
