It Was Basically Merge Sort

Regular developers measure performance in milliseconds or microseconds because that's what modern tools show them. Meanwhile, the true optimization psychopaths are counting individual CPU clock cycles like it's 1982. They're the ones rewriting entire functions in assembly just to save 3 cycles in a loop that runs twice a day. The difference between "fast enough" and "I need to know exactly how many nanoseconds each instruction takes."

Game developers will casually implement particle systems that simulate volcanic eruptions with real-time physics calculations, write custom shaders that make demons emerge from interdimensional portals, and handle complex collision detection for massive explosions... but ask them to make a scarf drape naturally on a character model and suddenly they're questioning their entire career choice. The brutal truth? Cloth simulation is genuinely one of the hardest problems in game development. While spawning a demon is just instantiating a prefab with some particle effects, fabric requires real-time physics simulation of thousands of vertices, collision detection with the character's body, wind dynamics, and making it look good at 60fps without melting your GPU. It's the difference between "cool visual effect go brrrr" and "I need to understand tensile forces and material properties now." Turns out summoning hellspawn from the depths of the underworld is easier than making a piece of cloth not clip through a shoulder. Game dev priorities are wild.

Oh honey, you think importing libraries for random numbers is the sophisticated approach? *dramatic hair flip* Meanwhile, the ABSOLUTE PSYCHOPATHS who hardcode their own random number generators without ANY external input are lurking in the shadows, cackling maniacally! They're not just playing with fire - they're BATHING in gasoline while juggling flaming chainsaws! The sheer AUDACITY! The MADNESS! Writing your own pseudo-random algorithm is basically telling the universe "I don't trust your entropy, I'll make my own chaos, thank you very much!" It's the programming equivalent of refusing to use a map and instead just FEELING which way north is!

The four stages of accidental coding genius! First, pure dread at implementing a complex feature from scratch—standard Tuesday morning existential crisis. Then somehow you bang out the code in a day (fueled by pure panic and energy drinks). But wait—it actually works on the first try? That's suspicious. And finally, the cosmic horror moment when you realize your hastily written code somehow handles edge cases you didn't even think about. Either you're secretly brilliant or you've created an eldritch abomination that will eventually gain sentience and destroy your codebase. Probably both.

So someone submitted an AI-generated assembly patch to dav1d (a video decoder), and it was slower than C. Let that sink in. Assembly—the language you write when you want to squeeze every last CPU cycle out of your code—got outperformed by C because an AI wrote it. The entire point of hand-writing assembly is to achieve performance that compilers can't match. You're basically telling the compiler "step aside, I'll optimize this myself." But AI-generated assembly? That's like hiring a robot chef to make instant ramen and somehow ending up with something worse than the microwave version. Turns out AI doesn't understand cache lines, instruction pipelining, or the dark arts of SIMD optimization. It just vomits out syntactically correct assembly that runs like it's stuck in molasses. Modern C compilers have decades of optimization wizardry baked in—AI has... vibes.

You spend HOURS psyching yourself up to finally conquer dynamic programming, ready to unlock the secrets of the universe. You click on that tutorial with the determination of a warrior entering battle. And then—BOOM—first sentence: "so we use hash set." That's it? THAT'S the big secret? The confusion hits you like a freight train. The cat's bewildered stare is literally your brain trying to process how something that sounds so intimidating boils down to... data structures you already know. The gap between the mystique of "dynamic programming" and the reality of "just memoize stuff bro" is absolutely sending me. 💀
