Personal Digital Brain

 

Thinking about the advancement of PDAs, Mobile phones, and other personal assistant type devices. How far could they go? This sounds lame but "In the future" peoples brains could be mapped to a neural net, and stored in a portable device, a PDB(rain) if you will. An example of its use would be to keep your dead wife in your pocket, and communicate to her as if you were sending a text message or talking to her on the phone, neat huh?  Of course the person would not have to be dead, it would be good to have your bank manager with you when you want to make a big purchase! You could have more than 1 brain in there and they could compete for the best deal like the President Reagan and Ayatollah Khomeini electronic waiters of the '80s cafe in the film Back to the Future 2.
