You’ve Never Seen LuaJIT Like This. AI Just Gave It a Secret Weapon.
A solo developer used AI to bring native SIMD—hardware-level CPU parallelism—to LuaJIT, achieving C-like performance from a scripting language. This isn’t just a technical achievement. It’s a fundamental shift in who gets to optimize hardware, proving that AI can act as a backend compiler engineer for any language, no corporate team required.
