Not sure! We are using it in (non-academic) CFD work.

Hard to say, but I'm looking at 39 contributors, 539 stars, 3,005 commits [1]. Nicely documented, pretty extensive list of users, CI on Linux and Windows. But with that said, yes, I've also dealt with absolutely horrendous academic C++.

I've used some quite reasonable academic C++ for geometry processing and meshing.

> I tried to talk the Go and Rust people into putting in multidimensional arrays, but the discussion degenerated into bikeshedding, with arguments for fancy but slower representations so you could take arbitrary N-dimensional slices from a multidimensional array.

This is the most frustrating aspect of Rust, to me, as a developer of scientific software. Rust has great potential to challenge Fortran in this domain, but numerics is mostly an afterthought in Rust.
