You see, history has historically been how we choose what data to forget. Our brains work that way too. We don’t form memories to write our stories. We write our stories to suppress inconvenient memories. If you ever go spelunking in the Big Data dump that is your subconscious, you will find a spaghetti landscape of crime-scene tape. History is the technology of forgetting, not the technology of remembering.
