its just I want to not have to depend on another/someone else's product. What happens if NASM goes poof?
Then why even write in x86 machine language? Go mine copper and silicon, reinvent modern electronics, design and build your own computer from scratch, and program it in its own machine language. Bonus points if you invent a superior alternative to the transistor in the process.
And none of that buying mining tools BS. Go find a few rocks and sticks and build up from there.
