My big problem with writing science fiction is that I have trouble believing what already exists, let alone imagining the world beyond today. Take 3D printing as an example. In a few years, before committing to building a new home, you'll be able to print out a 3D model of it at your desktop. Or design a figurine on your computer and have it printed out. If we get to the point of scanning bodies--maybe not at home, but at a photographer's studio--then we'll have a 3D rather than 2D (photo) record of our families and ourselves, not to mention our pets, at different ages. It's not just movies going 3D.
