Agreed. The world simply becomes different. I had volunteered, as I studied engineering in the past to give 3d classes to kids for free. We have PhDs like ObiJuan making videos and releasing them over the net teaching FreeCad, OpenScad, how to do robots and so on. The children we teach today (10 ,11,12,13 years old and older) are incredible. They do create their own toys. When this people get to 18 or 20 years old, "real engineers" but with no real experience prototyping because it was simply too expensive to fail, will not be able to compete against them. People will be able to prototype their own small cars soon thanks o sharing sites like thingiverse, youmagine or github. There will be Linus Torvals of hardware soon.
