I strongly dislike CUDA. Once you have allowed that proprietary cr*p into your C++ codebase, it is very hard to get rid, and you end up with code that is either tied to a single vendor or an #ifdef hell, probably both.
The best way to program GPUs is face up to the reality that they are not the same machine as the CPU, write your kernels in separate files, and launch them manually, like in Metal, OpenCL, and D3D12, etc.
These days we even have DSLs like Triton that make kernel writing much more ergonomic than anything you would hope to achieve in Rust.

Genuine question...why not just type "crap"? It's not even that much of a curse, but I've never really understood the point of self-censorship. If you don't want to curse then you could just use a non-curse word.
Because I know it is not technically crap, a lot of competent people worked on it, most with good intentions. I suppose it is better described as a cleverly designed Trojan horse than can infect your software and make that software become crap, in the sense that it becomes harder to maintain, increases code duplication, messes with your build system, ties your build system to platforms that have their toolchain binaries available, etc., etc., without bringing any long-term benefits over learning things the hard way.
The long term benefit is that there are more developers with CUDA experience available to hire than there are with any of the "hard ways" you mention.
Not saying you're wrong, but my career got a lot less frustrating when I started focusing more on the product and less on the ergonomics of the implementation. If you need to build a house and the customer isn't willing to pay for brick, you use vinyl siding.
