Imagine a utopian future where the -o4 optimization flag actually exists. We're talking about a world where your code doesn't just run fast—it achieves sentience, solves world hunger, and probably fixes your merge conflicts too. Currently, GCC and most compilers max out at -o3 , which is already aggressive enough to make your binary unrecognizable. But -o4 ? That's the stuff of legends. Flying cars, futuristic architecture, and code that compiles without warnings on the first try. Pure fantasy.
