alt Hacker NewsAs a 10y old, my father taught me about logical ports. I took a very large piece of paper and in a few days, I designed a tic tac toe "computer". It had LEDs that indicated the next computer move, based on the position of the pieces: every single possible state of the board led to a specific "next move" led. I do not think it actually would have worked, but of course I was very proud of my design at the time. Unfortunately, when I showed it to my teacher, he did not believe that I was serious. "This is a joke, right?" And that was it. Poor kid me... It did not discourage me however. I was a software engineer for a long time, and now I am a CS teacher. And I (try to) never ever discount the efforts of children.

One of the things that got me in to "coding" when I was 9 years old was building tic tac toe in Excel, locking the window size to 3x3 cells and then implementing clicks as links to the next board state, with the "computer" having already played the next move. The whole sheet had every possible board state written out by hand.
That really hits home. I spent a couple weeks in primary school sketching my own blueprints for great inventions. Nothing that could've ever worked (I didn't know what a transistor actually was, but my machine certainly had a lot of them!), but in hindsight a good start for a curious tech-minded child - switches that opened/closed circuits, wires to connect the various imaginary lasers and electromagnets, and so on. On the back of the paper I scrawled documentation to remember what the darn thing was actually supposed to do (the biggest one? Save people who fall out of airplanes, which to my 9 year old mind was a big issue that needed to be solved)
One day my teacher noticed me doodling in the back, so she promptly grabbed all the "blueprints" I was so proud of, tore them up, and tossed them in the trash. I guess I get discouraged easier than you though, since I didn't design a thing for many years afterwards.
