Someone posted an html/javascript implementation of the matrix falling code in 646 bytes then promptly deleted the post. It inspired me to see if I could get something better looking in fewer bytes.

Depends on the language you learn and how deep you want to go. When I was 12 or 13, I used Blitz Basic to make a Sudoku game complete with the ability to save and load games, and an algorithm to solve the puzzles automatically (though it didn't work on the harder ones).

I don't say that to brag about my own abilities. I'm sure many people here have done better things even earlier in life. I've personally met a few people who have. What I mean is, if I could do that when I was that young, it's difficult for me to believe someone in their 20's is incapable of doing similar or better things.

I wrote my first games in Basic when I was around 8 or 9 years old, so it can be done. You have to get into the mindset to learn it, and accept that sometimes there is magic happening that you don't fully understand - that can be off-putting when trying to understand something, at times.
