Dropping to unsafe rust is quite easy as long as you understand what you're doing (and reading pointer is generally unsafe).
In the case of automatically upgrading from int to bignum, or green threads, going lower level would be much harder.
I just wish Rust stayed focused on being the best systems level programming language (for example finishing the SIMD package, getting into stable Rust, getting language level GPU integration similar to CUDA / OpenCL).
PyToch, and now the newer GGML for example is still written in C++ for example
I still like the changes being made in the language, just not the focus.
