I had to laugh at this really, really hard. Thanks!

My understanding of GPU shaders is limited, but isn't it kind of their point to be (incredibly) fast, small and, most importantly, finite, otherwise the performance tanks too hard?

Loops: yes, but this is supposed to be enforced at the shader compilation point, and it seems that SPIR-V does not prevent describing a shader which is an infinite loop. I did ask codex about this, which output I will not paste here, instead referring readers to 2.11.3 of https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.htm... (warning: very complicated)
