I think the future is getting rid of all the APIs and driver overhead, compile directly to GPU compute and write your own software renderers in a language targeting GPUs (Could be Zig)

A better way to think about the problem is to recognize that the APIs and drivers are providing various services that pretty much every user is going to need, and which you will now need to reimplement yourself.

Nobody needs all of Vulkan, but everyone needs quite a bit of it. Buffer allocation? Command encoding? Scheduling? Synchronization? Abstracting GPU architecture differences (and GPUs vary a lot)? Render pipeline fixed-function stages like primitive assembly, tiling, and blending? You're signing up to implement all of that - good luck!

In this view, your idea is the assertion, "I could do a better job at all that stuff than the driver developers." Maybe so! They're only human. Drivers do have bugs. But you're only human too.

		I agree; however, engine developers are already dedicated to building massive behemoths of software that is the game engine and they constantly do collaborate with driver devs, essentially sharing much of the same skillset. Also, the onus is actually on the GPU manufacturers (not game engine devs) to simplify the programmability of the GPUs to the level we have for CPUs (we also do not write microcode, however, the programmability is much much simpler with access to good compiler toolchains). This will massively help non game engine developers who need GPUs for other kinds of compute.
