The next revolution is happening right now- it's consumer level 3d printers (cupcake, reprap etc) and they're going to change everything, more than computers and cell phones combined did.
So the 3-D printing industry doesn't have its Apple ][ / Pet / TRS-80 yet. In the computer industry, back in '76, those were only a year away. And then in 5 years there was the IBM PC, in 6 years the Commodore 64, and in 8 years the Macintosh, and suddenly these little machines were everywhere.
Is 3-D printing going to advance that quickly? I doubt it. The technical challenges, and especially the price issues, look pretty tricky. I do think we'll get there before too long, though. It should be interesting to watch.
