Apple's Metal API suffers from a weak ecosystem of third-party documentation and examples (unlike OpenGL), and Apple's documentation is barebones, so having a tool like ChatGPT that can interact with that entire space conversationally is a huge boon.

Sometimes it suggests erroneous approaches. When that happens, I can ask it for alternatives. It's not actually too troublesome to vet the information since it has to actually work on the hardware, and honestly, I feel like I'm learning it more deeply by trying the different ways anyway.
