Enhancements in the cost, durability, and miniaturization of recording & storage medium will result in most people casually recording events around them almost continuously, with serious positive and negative effects on everything from crime & health to privacy & social relationships. Because this would be a digital and chronologically stored archive, search engines would be tailored to index and locate data in a fashion more consistent with human memory and objectives, such as a rapid search and recall of where you left your keys, how many times you ate a given meal, how many calories you consumed or steps you have taken this month, or what that joke was that a friend told you at a party last year and you can’t quite remember. Further ahead in time, improvements in Artificial Intelligence or Mind-Machine interfaces could cause this to be more like a personal assistant or a direct interface into your normal memory and recall.
