You need to keep up. The NSA has been intercepting machines and mod’ing them before they are delivered to the customer (no, not us low level peon’s posting on FR but some key targets and some key geography, yes).
Maybe we'll be going back to building our own computers from component parts, but then you would have to know enough to ensure there wasn't something embedded in the components..
My computer is older than dirt, so it was probably clean until NSA came to my house.
