Similarly, if people are interested, I have coded the possibility to compress zip files on several cores in zip.js [1]. The approach is simpler as it consists of compressing the entries in parallel. It still offers a significant performance gain though when compressing multiple files in a zip file, which is often the nominal case.

You don't need to use C++ to interface with CUDA or even write it.
A while ago NVIDIA and the GraalVM team demoed grCUDA which makes it easy to share memory with CUDA kernels and invoke them from any managed language that runs on GraalVM (which includes JIT compiled Python). Because it's integrated with the compiler the invocation overhead is low:

And TornadoVM lets you write kernels in JVM langs that are compiled through to CUDA:

There are similar technologies for other languages/runtimes too. So I don't think that will cause NVIDIA to lose ground.
