Damn, that's interesting!

Kind of makes me think about comparing the very fucking long period of time before agriculture where humans were just monkeying about compared to the shorter period of time afterward with a lot more people and then even the relatively quite fucking short modern period with even so many more people. When you think about the rate of change of human living, for instance, how fast it is now; is that just because there's so many more of us? I mean there's more of us because of things like the agricultural and industrial revolutions, but is it also a bit of a feedback loop? There are perhaps some frightening connotations to that - but to say my actual point, maybe it's appropriate to think about the "amount" of history in human-years rather than just years.
