We make judgements faster than ever, think about things less while concluding more, and communicate in a limited number of characters our most important thoughts of our life or of at least the last half hour. Diaz, in the last few pages, tells us both how sure we are of what we see and how irretrievably wrong we are almost always as we take a few facts and fill in, wrongly, with whatever we are quite positive to be correct. Brilliant bending and aligning the web. Lesson learned.
