Of course it is a skill issue, I'm not afraid of admitting I'm not smart enough for Vulkan. That so many people have skill issues is the reason why Cuda trumps and will continue to trump Vulkan despite being vendor-locked. If you want people to actually use Vulkan, you need to remove barriers to skill-issued people like me. Poor third party wrappers like VMA that barely address one out of hundreds of issues aren't going to accomplish that, you need to resolve barriers in the core API. With a design like Cuda where there is always a default easy path, and a complex but optional path.
