Error Code: 404

With the advent of the AI ​​era, artificial intelligence has appeared in more and more places, and massive amounts of data are being created every day. As a bottom-level data cleaner at a major AI factory, my task is to clean this data. Noise, afterimages, misidentified targets, abnormal images... Anything that cannot be understood by AI will be classified as junk data and await deletion. Over the past three years, I have deleted countless abnormal records. Until one day. Abnormal data from a sweeping robot that was returned one after another was sent to my workstation. User complaints are surprisingly consistent: It always crashes and spins crazily late at night for no reason. It always slows down and avoids the air. There will always be vicious system errors that cannot be cleaned. I thought it was just a common sensor failure. Until I bring up the background log. LiDAR shows the presence of obstacles. Infrared video showed nothing. However, the error code prompts: [The target exists and cannot be defined. From that day on. More and more smart devices from all over the world began to upload the same abnormal records. It's as if something has always existed in reality. It's just that humans have never seen it. And artificial intelligence has discovered them first.
