The problem with Vulkan and the similar APIs is that the authors of the specification attempted to make an industry standard that would be easier to implement by the GPU manufacturers, but at the same time it would still be quite high level and abstract so that the end users could use it without care of how the devices work in too much detail.

The issue here is that if the users chose Vulkan, they probably do care about these details, but the API makes it totally obscure for them if they don't have prior experience with the GPU architectures.

At the same time the API is too low level for other users who want to just start drawing polygons on the screen here and now like they did with OpenGL.
