When I was very little my mom brought me to visit a preschool, and while we were there little Scott saw 2 things that made me want to go there. One was a cool loft reading area, and the other was a computer.
That computer was an Apple 2. A device that launched me on a life being excited about the things that could be done with tech. It seemed endless, what you could do, and compounded by the fact that they never let the kids use the computer, it gained mythical status in my psyche. The next year though I finally was able to play with one, and it was fantastic. You could play games and look at pictures, and, if you could figure it out, there was a language that could make the computer do almost anything.
I used a lot of different computers over the years, but that one opened the door for me.
I obviously did not know Steve Jobs, but if you want to see evidence of him changing the world, you can look back to a little kid who got into technology in the year 1987 because of an Apple][.
