To compare the 3D printing of the 1980's with that of today is a stretch, at best, both in quality and price. And people who care have been '3D printing' (high quality, like with laser sintering, not Makerbot crap) for years. It's disingenuous to suggest that the very first moment something has been shown in a proof of concept should be the moment that everyone starts rejoicing and flocking to it en masse. Many technologies need years or decades to get mature enough for wide spread use (which the author seems to equate with 'getting recognition').
