Who is we here? I'm curious to hear more about your ambitions here, since surly pulling in wgpu or something similar seems out-of-scope for the traditionally lean Rust stdlib.
Agreed, I don't think we'd ever pull in things like wgpu, but we might create APIs or traits wgpu could use to improve perf/safety/ergonomics/interoperability.
Get Nvidia, AMD, Intel and whoever else you can get into a room. Get LLVMs boys into the same room.
Compile LLVMIR directly into hardware instructions fed into the GPU, get them to open up.
Having to target an API is part of the problem, get them to allow you to write Rust that directly compiles into the code that will run on the GPU, not something that becomes something else, that becomes spirv that controls a driver that will eventually run on the GPU.
Hell will freeze over, then go into negative Kelvin temperatures before you see nVidia agreeing in earnest to do so. They make too much money on NOT GETTING COMMODITIZED. nVidia even changed CUDA to make API not compatible with interpreters.
It's the same reason Safari is in such a sorry state. Why make web browser better, when it could cannibalize your app store?
Hmm. Maybe the opportunity would be more like AMD, Intel, and the various AI labs and big tech get together, and by their powers combined figure out a way to stop giving NVIDIA their margin?
Somehow I want to believe if you get everyone else in the room, and it becomes enough of a market force that nvidia stops selling GPUs because of it, they will change. Cough linux gpu drivers
Effectively standardise passing operations off to a coprocessor. C++ is moving into that direction with stdexec and the linear algebra library and SIMD.
I don’t see why Rust wouldn’t also do that.
Effectively why must I write a GPU kernel to have an algorithm execute on the GPU, we’re talking about memory wrangling and linear algebra almost all of the time when dealing with GPU in any way whatsoever. I don’t see why we need a different interface and API layer for that.
OpenGL et al abstract some of the linear algebra away from you which is nice until you need to give a damn about the assumptions they made that are no longer valid. I would rather that code be in a library in the language of your choice that you can inspect and understand than hidden somewhere in a driver behind 3 layers of abstraction.

I agree that, that would be ideal. Hopefully, that can happen one day with c++, rust and other languages. So far Mojo seems to be the only language close to that vision.
