HPC researchers already employ some techniques to detect memory corruption, hardware flaws, floating point errors, and so on. Maybe Rust could meaningfully reduce memory errors, but if it comes at the cost of bounds checking (or any other meaningful runtime overhead) they will have absolutely zero interest.

Chapel and Julia ongoing efforts proves otherwise, and I can tell from CERN days, not everyone uses those tools.

In any case, that means those languages are much better positioned than Rust in such ecosystem.
