As for the actual article, this:

“3D printing will be poised to suck the value out of manufacturing.”

Sounds like a good thing to me. If we make all our own jobs obsolete, then our economic model will have to change so that we don’t starve to death in the ensuing abundance and leisure.

Of course, just because manufacturing and, say, agriculture can be done by automatons doesn’t mean they should be. Even if some can’t fathom it, a lot of people genuinely enjoy getting their hands dirty. Will they be allowed to farm for pleasure when the robots do all the necessary farming?
