The brain is just like your body, if you don't use it regularly, it will lose efficiency and will decay. This project is not going to help as people we'll rely more and more on devices rather their own memory.

I thought toes will be the part of the human body that will disappear progressively as a result of the modern life but it looks like the brain is a good contender too :-D

Microsoft researcher wants to back up your brain.: "'The quest is to essentially build a surrogate memory. Something that's as good as my own memory, that I can use it as a supplement, and will remember everything that I should have remembered, that came to my ears, eyes, whatever,' Microsoft's Bell said of his experiment."
