Self-taught hardware engineer discovers that GPUs really are ridiculously complex and hard to design after all

Anyone who has studied electrical engineering will know that with the right tools, know-how, and a lot of perseverance, it's possible to design a basic CPU from scratch. It won't be anything like today's processors, of course, but what about GPUs? Surely they can't be any different, yes?
