This topic has somewhat recently acquired a connotation where it yields a polarized response. People seem "tired" of the language and the episodes like Bun rewrite don't help, especially in current LLM-obsessed era.

Amidst this, just let me try to give my own experience with language while working in a field where it doesn't have much traction (scientific/numerical programming). A couple of years ago, after being tired trying to make Python faster, I was looking for a language to write simulation code in. Fortran (and C/C++) has been the go-to choice in my field for decades but I wanted to try a modern language. I tried Julia but the workflow didn't come naturally to me. Also by default, it also wasn't ahead-of-time compilable. Rust was my second choice but it's type system/design, expressiveness and tooling (rust-analyzer) won me over. I have written so much of it and I really enjoy writing it. Borrow checker isn't really an issue 99% of time when writing scientific code. And when it is (self-referential data structures), you can just use an arena (or something equivalent). The C/Fortran inter-op is great so it's still so easy for me to build my own abstractions on top for the more general stuff like solving ODEs and sparse matrices.

And of course, there is speed, memory safety and ability to parallelize things so effortlessly (rayon is magical), but I feel those were never the things that actually won me over. The language was just a joy to write.
