and rarely if ever true at personal/family level (most people don't think their phone/tablet/laptop could lose their data; most people don't think of their data past photos they took this week - "Oh it's OK to lose... wait, my tax documents are gone? Photos of my baby from two years ago are gone? My poems are gone? My [.. etc] is gone???"?).
