Same. GPU in particular, seems like magic to a layman’s eye like mine. Bluetooth and WiFi reverse engineering is something I can conceptually grasp from afar, especially because they should be relatively similar across architectures. They are well defined protocols, you send and receive packages. OK. But GPUs are such complicated beasts, each on it’s own snowflakey way, I don’t even understand how the work on a deep level, let alone imagine how reverse engineering would begin. Memory access and sharing with the CPU, shaders, a massively parallel computing model. Crazy stuff. Oh, and you also get to draw lots of triangles really fast while you’re at it.
