Jorge Luis Borges wrote this really good fictional short story in 1944 called Funes, the Memorious. It's about a boy, Funes, who isn't incredibly bright until one day he falls off his horse and hits his head. After the accident Funes has finds that he suddenly has an amazing memory with which he remembers every single detail of every moment in his life.
His memory is so vivid that at one point he sees a dog, and a moment later the dog seems different. Funes remembers the way each hair stood on the the dog's back, the direction of the breeze, what direction the dog's tail was pointed, the perspiration on his own body, where everyone else was, etc. That dog could not possibly be the same dog that he saw a moment ago.
Funes not only remembered every leaf on every tree of every wood, but even every one of the times he had perceived or imagined it. He determined to reduce all of his past experience to some seventy thousand recollections, which he would later define numerically. Two considerations dissuaded him: the thought that the task as interminable and the thought that it was useless.
Trying to Remember Too Much
At this day and age, when so much of everything is stored in database and everything is logged, is it possible to remember too much? Technology has enabled us to surveil others, video tape every moment of our life, store every email, take a seemingly endless river of pictures, record conversations, and log data out the wazoo.
Sure, it's great to have it, but what use can you make of a year's worth of data? What about ten years? Or dare I say, a century's worth of data?
This is when visualization becomes important. It's our duty to make the ocean of data available without letting the ocean's never-ending vastness overwhelm the data explorers. Otherwise, our technological memory becomes like that of Funes', and all is lost. OK, cue the dramatic music... now.
