No matter how highly automated you can make an experience, not a single thing beats real, true interaction.

I think about going on a morning run with a step counter that is programmed to notify me when I've reached my desired time/distance and heart rate. The digital fireworks permit me to own a smug sense of accomplishment. But you know what beats that? A random thumbs up and high five from an unknown pedestrian. "You can do it!" she cheers. "I will, thanks!" I wave back. This genuine, human interaction is more satisfying than the vibrating wrist alert. If we could put that magic in a bottle, we would alway have something authentic.
