Hm, comparing developments spanning from the 12th century up to now with stuff that is happening in the last decade. Just give social media about 5 or 6 centuries to develop, and then check back to see if the arguments of this article are sound.

Edit: sorry for being so dismissive, but I just can't stand rhetoric that says something about "us" and "we". There were seriously stupid people back when we supposedly had larger attention spans. There are still stupid people now.
