Document everything and your world is a perpetual crime scene. The past becomes a fixed point of reference rather than a vapor trail behind you. I can *prove* to you the shutters of the house around the corner used to be maroon and pink. I can *prove* to you we ate lasagna for dinner last week.I can *prove* to you I once stood in front of the Eiffel Tower.

Now snapshots elide the law of diminishing marginal returns. One image will not be stacked in a shoebox with seven hundred other pictures. It will not be found inside an envelop the drugstore clerk handed you with the negatives tucked in the front like you’d ever print it again. The image is a piece of your shadow, not a strip of paper that you can count. We are talking about ether, broken down by batch uploads or sorted with tags, but absent physical dimensions the images are pieces of a whole. One collection for one life. Some parents even post their sonograms and tag them on Facebook. A kid today could construct a flipbook autobiography from the womb until death.
