An interesting article in Time‘s July 6–13, 2015 issue:
The Old Answer to Humanity’s Newest Problem: Data
“When humans first evolved, food was scarce; now we’re suffering from an epidemic of obesity. In much the same way, we’ve gone from a world where information was hard to find to one where it’s everywhere, in staggering quantities. Eric Schmidt, former CEO of Google, once estimated that every two days humanity creates a quantity of data equivalent to the entire amount created from the dawn of time up until 2003. And he said that five years ago. Cognitively, we’re not evolved to handle this.”
Go look at the issue to see the accompanying graphics.
OTOH, disappointing to me was I saw no mention of Edward Tufte. You may recognize this graphic he uses in his advertising.
