You seem like a really nice person with similar interests as me, I'd love to actually get to know you :)
I started out with C, definitely didn't know how to write multithreaded code when I was 10 haha. I learned most of that after reading a great book on operating systems (Modern Operating Systems by Andrew S. Tanenbaum) a couple months ago.
I'm trying to clean up my Github, you'll notice the "DayN" repositories are just edited versions of stuff I found online to learn from. These days I create my own projects, and am slowly deleting those "learning" repositories and making them private.
Perhaps you are just 10x more capable at this than all other humans I've encountered in my entire life. If so good luck and godspeed and please try to avoid bringing about AI takeoff for the rest of us :)
