The only reason I mention it here is that it had an interesting sci-fi technology:
I envisioned "nanocells" on my own a few years before this film was released. They struck me (and still do) as one way to achieve medical immortality. A person would be injected with an engineered virus that would travel to their brains. It would infect their brain cells, and as it did, each infected cell would slowly "transform" into a functionally identical synthetic cell that would be of much more durable construction and have a tiny computer inside of it. The 3D structure of the person's brain and the patterns of interactions between his cells wouldn't change, so the person wouldn't realize anything was happening during it. Towards the end of the process (which might take years), as entire neural pathways were comprised entirely of synthetic cells, the person would notice a sharp speed-up in the specific types of cognition dependent upon those pathways.There are two games that dominate the world of Gamer: Society and Slayer. In both of these games, the human actors who actually perform the physical actions of the game have no free will. Thanks to nano-implants, they no longer control their own bodies and motor actions. Rather, they are forced to take orders from the gamers “playing” them. Artificial nanocells are introduced into their brains; these cells reproduce, replacing the original, organic nerve cells with synthetic ones. Once you have undergone this procedure, you have an IP address in your head, and your body obeys whatever commands are transmitted to that address by the player who controls you. You say what they say, and move the way that they want you to move. Of course, this only works one way: actors can’t see or hear their controllers, but the controllers are able to live vicariously through them.
Synthetic cells would be capable of sending and receiving electronic communication, which, among other things, is an ability that would enable them to report their positions relative to each other along with their typical patterns of activity. A person with a synthetic brain could thus save backups of his brain and mind onto another device. If part of his brain were ever damaged, he could use the information in the backup to reconstruct it exactly.
The synthetic brain cells might even be motile, meaning they could reposition themselves relative to each other if it were advantageous to enhance or weaken specific mental processes.
