Might be of some curiosity:
I quit my job to focus on SerenityOS full time
Hello friends! :^) Let me tell you a story…

Yeah amazing that one guy wrote an entire OS, the guy even wrote his own compiler. Agreed that is said how his life ended, the guy should have been in a mental hospital he seriously needed some help which he never got.Yeah, TempleOS. I've run it i a VM and it's impressive what one man did. It's kinda sad though how his life ended up.
I haven't run Serenity OS, but I've heard that he just was tinkering around with stuff, and I was like "Whoa! If he calls writing a display system tinkering around, he's incredibly good!"
