In an excerpt from his new book Talking to Robots, David Ewing Duncan imagines looking back from a future where memories can be permanently stored with the help of a technology called Memory Bot based on an actual conversation he had with Ken Goldberg, Tiffany Shlain, and Odessa Shlain Goldberg. Yes, there really was a time when people were expected to preserve memories on their own. A time when you would share with your four-year-old daughter a stunning sunset and it wouldn't be automatically recorded as a neural-meme. You felt so very close to your little one and she to you, only to have that moment vanish forever. Maybe you took a selfie, but that never really captured the whole experience.
