You don't have a tiny brain--programming Vulkan/DX12 sucks.
The question you need to ask is: "Do I need my graphics to be multithreaded?"
If the answer is "No"--don't use Vulkan/DX12! You wind up with all the complexity and absolutely zero of the benefits.
If performance isn't a problem, using anything else--OpenGL, DirectX 11, game engines, etc.
Once performance becomes the problem, then you can think about Vulkan/DX12.
