3D printing, digital audio, and other current technologies are almost certainly going to make copyrights only effective at stopping mass monetezation of copied content - not at stopping the copying and sharing of content for personal use.
3D printers in particular, I believe, will trigger the decimation of the scale model and toy markets as we know them. The only vestiges which are likely to survive will be those requiring a high number of moving parts, motorizations, and more.
