Today, we have the opportunity to go back to the slide-rule era, at least in terms of getting a feel for how engineered systems will behave. We can do full-scale simulations that tie together math with physical demonstrations. You can show things quickly in a physical form with little extra effort. So we can return to seeing the math working and to doing what engineers really bond with, hands-on work. Yes children do have a RIGHT to the best that humanity can offer like it or not. the amazon tribes you refer to are cut out of civilization not out of respect for their culture but out of guilt or worse out of scientific interest. let THEM decide if they like malaria and crude meat after they are given a choice. and even if they do prefer their ways what do you do if they start to die from an epidemic? let them die or give them some penicilin even if they don't like it? .

Twenty years, I was playing with Linux 0.0.x and starting an ISP business. My good friends and colleagues were all telling me that Linux suck, that SunOS has this, BSDi has that, 386bsd has other, etc. etc.. All of those have problems: cost, expensive hardware requirements (Solaris, SunOS, AT&T SysVRx.x), and the BSDs had legal problems. Once all the design, building, re-building and testing was done, I finally had a finished Lego Computer that I was happy with – even if it took longer to complete than I originally planned. Being pleased with the final product was so much more important to me than the endless hours I spent tinkering. And I'm happy to say that I've met all of my initial criteria – and then some – to produce an affordable, durable, reliable small form-factor computer system with a unique aesthetic that appeals to a broad audience and is capable for essentially all computing tasks. .
