It absolutely isn't. After having spent 5 days not getting anything done in Vulkan, and being able to implement that same thing in a single day in Cuda (no prior experience in either API), I decided to never ever use Vulkan. It's a hopelessly overengineered API that is in dire need of a successor.

I may give it another try once it does not require a wrapper before it is remotely usable. I.e., once it has a single-line malloc without the need for third-party libs; default queues so I don't need to query and select queues; implicit sync by default and explicit sync by choice; NV-style bindless (i.e. no descriptors, just a handle); and so much more.
