text: Lets also not forget that computers and other devices malfunction quite often, more frequently then we'd like to admit. Have you ever been on your laptop while constructing an important document and your system just completely shut down without saving? That has happened to me and many people I know and we all thought it was one of the worst things that could happen. Can you imagine what would happen if you're on the middle of the expressway taking a nice road trip with your family and your car just shuts off in the middle of the highway surrounded by 10 ton trucks that could crush your small self driven car like it was an empty soda can. I can risk losing papers on my hard drive due to a malfunction, but im not willing to risk my life to one.
