That's a great point, and illustrates that blinder effect discussed in the article. The Blackberry executives and engineers also did not think that the iphone would sell well at a higher price point and a lower battery life. My point in bring up all of this is that the key insight in this article is not about disruption, but about refactoring your base assumptions. When you see 3D printers as to what is really is, but has not yet been, then you start to see other technologies that are coming together to be able to fabricate things in your garage. Yes, that does include being able to print circuitry directly into the printer -- and yes, there are people working on that right now. This is a lot closer to happening than you think it is :-)
