Just like the movie *The 6th Day*, with Arnold Schwarzenegger, the technology to download someone's memory and put it on a harddrive/chip exists right now. The chip(aka soulstone) can then be implanted in someone else's brain which then completely takes over their mind. These are called *Chipheads* by whistleblower [Donald Marshall](http://donaldmarshallrevolution.com).
