The main reason is many companies have a lot of C/C++ devs or other devs learned Rust, so they don't have to hire new Rust programmer. There are many places using Rust, you should check this out: https://www.rust-lang.org/production/users

That is the case here to some extent. Projects have been done in rust, but "rust programmer" isn't what we seek.

Jumping into rust for our major projects doesn't make sense. Existing code is largely C, with some assembly and C++, so rust would just add another language to the requirements.

To somebody who isn't already a rust expert, it isn't even clear that rust is good for the job. We like bitfields as L-values in C, without ugly macros or other wrappers. We like to be able to easily produce a small relocatable blob of binary executable code, such as a firmware image or boot loader. Speed and size matter to us. Sometimes we compile for weird targets such as ARMv4, Coldfire, 80286, and Xtensa.

C certainly isn't perfect. If rust had fewer limitations, that could be convincing. My wishlist is probably zero-priority, but FWIW: I'd like pass-by-value arrays, naked functions, easy ability to get things in place as desired (position independent or fixed) without a PLT or GOT, portable bitfield layout, specified calling conventions, computed goto, and other things that high-level programmers despise.

The above is also certainly non-exhaustive. Google isn't on the list, and they are using rust in fuchia.
