Heard the same thing five years ago, when graphine was created, and that in just 5 years it would transform the world. A sheet of material one molecule thick and hundreds of times stronger than steel.
So far, nada, zip, zilch. Nothing really being manufactured with it.
And what about all of those tens of thousands of things that were going to be manufactured with 3-D printers, out of liquid steel. We heard about that 10 years ago. And again, except for a few oddities, nada, zip, zilch.
It take decades and decades for these inventions to reach a practical, affordable state in manufacturing.
(The only exciting thing about 3-D printing, is that they are now printing human organs with it. Of course, it only costs about $500,000 per. As of last month, it is easier to inject stem cells and grow human organs in pigs.)
