Comment Designing models for 3D printers (Score 1) 737
Today's mass-scale manufacturing will collapse, and needs will change, so my bet is that it will be very useful to be the guy who can design models to be fed to 3D printers.
This is going to become a useful skill anyway in the next few decades, so it's not a bad investment for a hobby today.
Will lawyers be useful? (I know many slashdotters will laugh and say we'll be better off without them, but the new forms of society will need new rules and a new justice system - and programmers would do this as badly as lawyers would program.)
