"The current state of the net, which wasn’t around before humanity established its existence, loosely forms a subconscious mind; one which is split off from mankind’s consciousness. This mental level net and the electronic network now cover most of the world. The subconscious mind they give rise to is done so in the form of the general consensus of the whole." - Ghost in the Shell, Stand Alone Complex: Season 2, episode 15
If it isn't obvious through the limited exposure you may have had to me through this blog, I am a fan of anime. Specifically, of philosophical anime with sci-fi themes. One of the shows that struck a chord with my mind is "Ghost in the Shell, Stand Alone Complex." The series is built around the idea that a collective subconscious can give rise to copycats that are mirroring each other while lacking a singular shared source to mimic. In other words, since the near-future society of the series is a place where the internet enables people to constantly share information with each other, multiple people arrive at the same conclusion simultaneously.
