that's what I think, too. Visicalc made computers to useful to people who moved lots of money and numbers around. What can 3-D printers do for people who move lots of money and numbers around.. can they help predict? can they simulate? can they help people compete? I hope so... the big thing many people miss with 3d printers is that they're excellent for making molds for better materials.
