The same applies to 3D printers today.<p>It is easy to mock this guy, specially the phrase of &quot;because I can&#x27;t imagine it, it won&#x27;t happen&quot; but at the time it did not exist so you had to imagine it, and most people can&#x27;t imagine.<p>Today people are saying exactly the same thing about 3d printers. Too expensive, lack of good software, and I can&#x27;t image people doing great things with this tool so it won&#x27;t happen. The center of the Universe for everybody is themselves.<p>We volunteer to teach children 3d printers now for a couple of years. Children that learned to draw simple things two years ago, now design complex things in freecad or Openscad with no effort whatsoever. For them things like sharing a design is so natural because they leaned it as children.<p>When these children grow up they will collaborate making cars or planes or fuel cells like we collaborate on Linux and is going to be huge.
