This is awesome! I wish I learned to code during high school. I can't imagine what level the next generation engineers/developers will be like if they start when they're teens. Limitless potential!
Many of us now in our 40s started on Commodore 64s, Atari 800s, Apple IIs and similar when we were actually preteens. I think starting relatively young is pretty normal for every generation of programmers actually.
Bit before my time, but that's probably true enough. The big difference is probably accessibility; there are so many less barriers to entry at this point, it seems like people are starting earlier than ever.
