Terrain-generation Memes

You spend weeks architecting this beautiful procedural terrain system with multiple octaves, fancy erosion algorithms, and biome blending—only to realize that literally everything you built is just Perlin noise with extra steps. The moon? Perlin noise. Mountains? Perlin noise. That cool cave system? Believe it or not, also Perlin noise. Perlin noise is the duct tape of game development. It's been solving our "make it look natural" problems since 1983, and we keep pretending we're doing something revolutionary when we're just tweaking the same algorithm Ken Perlin invented while working on Tron. Minecraft? Perlin noise. No Man's Sky? Perlin noise (with Simplex, but same family). That indie game you're working on? Yeah, you know what it is. The real kicker is that it works so well that you can't escape it. You try other noise functions, but you always come crawling back.
