I find the use of "extremely" to be extreme here or too forgiving of problems that arise while using other APIs. There are all kinds of state of the art algorithms implemented on top of Metal. But anything improper can easily switch off GPUs, you can even do that with CUDA.
That's fair, I've certainly also had problems with Vulkan drivers from other vendors. So I'm not saying it's more buggy than other GPU platforms, but it is buggy, and it is more buggy than we expect of CPU-based language toolchains and runtimes.

Unfortunately, that's the situation. Though in the last couple of years, there is a noticeable increase in tooling on all fronts.
Because one of the top complaints is how Vulkan is found lacking versus proprietary API SDKs, even with what LunarG provides to Khronos.
I'm hopeful for WebGPU in the future, not just for its features and expected cross-platform support, but because I expect a pretty thorough test suite to emerge, holding developers' feet to the fire to make their drivers actually work.
