How true! I couldn't afford a computer in 1977, so I bought a book in 1978 on how to program DEC PDP-11 in assembly language. I understood something for every 10 I couldn't grasp without a real computer. In 1978 I bought a Commodore PET with a cassette tape drive built into it. Learning was slow going. Even in 1995, I was still calling companies for information, unless they had a website (< 25,000 then). I've had the chance to do some cool stuff, because I tried hard to make those connections, whether it was writing a letter to a company for a sample-kit of their electronics products or something other. Now, my son, has made rockets with sugar fuel, build a robot controllable via the web, made magnet ski boots for walking upside-down on steel, etc.. all from YouTube and other sources. I think he is smarter than I ever was, but I also think the information availability (1 min. vs. 2 weeks for an answer by letter or phone), the amount of people publishing videos, how-tos and such, have greatly amplified the process. It is only a matter of time before we walk up the exponential curve of progress we are standing before today on a slight incline.
