I would love to be able to use Rust in my professional project. Unfortunately, I am doing high performance scientific computing. Rust doesn't even come close to offer any good alternative to cross-plateform, cross-device (CPU/GPU) libraries such as OpenMP Target, Kokkos, SYCL, ... I believe we need Nvidia/AMD to take Rust seriously (I'm not sure it is even possible without unsafe everywhere) to be able to offer good libraries.
In my world, using C++ is the modern language, because most project are stuck with Fortran.
