"There is nothing more foolish, nothing more given to outrage than a useless mob."
While there's no definite date on this quote from Herodotus' Histories, we know it was probably written somewhere between 450 and 420 BC, as the entirety of the text was written in that 30 year span. That would make it about 2,465 years old, give or take. We can also assume that Herodotus was not the first to make this assessment, but simply the first to write it down in a way that has been remembered.
Therefore, I'll make the modest proposition that this phenomenon is not particularly new, the video is not particularly enlightening, and that the creators might have been better served doing something more productive with their time -- like, to pull an example from absolutely nowhere in particular, reading the Classics, perhaps.
