Elon Musk wrote and sold his first piece of commercial software at age 12.
It was a video game called Blastar. He coded it himself in BASIC on a Commodore VIC20.
A South African computer magazine bought the code for approximately $500.
No internet. No coding tutorials. No mentors. No YouTube. A 12 year old boy in Pretoria who was being hospitalized from bullying taught himself a programming language from a manual and produced a sellable product before becoming a teenager.
The game is still playable online today. It is a simple space shooter. Nothing that would impress a modern developer. But the context makes it extraordinary: a child with no friends, no social life, and a father who told him he was worthless went home from school and built something that a magazine paid money for.
The computer was the only environment where his mind was matched. In the schoolyard he was the weird kid who talked too much about things nobody cared about. In front of the keyboard he was a developer shipping commercial products at an age when his classmates were playing with toys.
The same boy who sold Blastar for $500 at 12 sold Zip2 for $307 million at 28, PayPal for $1.5 billion at 31, and now runs companies worth over a trillion dollars combined.
The career started on a Commodore VIC20 in a bedroom in Pretoria. The scale changed by a factor of a billion. The dynamic never changed: a mind that could not navigate social reality but could build things in the technical world that the social world would eventually pay anything to own.
