And Vulkans unnecessary complexity doesn't stop at that issue, there are plenty of follow-up issues that I also have no intention of dealing with. Instead, I'll just use Cuda which doesn't bother me with useless complexity until I actually opt-in to it when it's time to optimize. Cuda allows to easily get stuff done first then check the more complex stuff to optimize, unlike Vulkan which unloads the entire complexity on you right from the start, before you have any chance to figure out what to do.

That's not realistic on non-UMA systems. I doubt you want to go over PCIe every time you sample a texture, so the allocator has to know what you're allocating memory _for_. Even with CUDA you have to do that.
And even with unified memory, only the implementation knows exactly how much space is needed for a texture with a given format and configuration (e.g. due to different alignment requirements and such). "just" malloc-ing gpu memory sounds nice and would be nice, but given many vendors and many devices the complexity becomes irreducible. If your only use case is compute on nvidia chips, you shouldn't be using vulkan in the first place.
