How does the language matter? I write software (mostly) in C for a living (the simple man's "embedded" as in "Linux on an ARM board", not the "bits on a micro controller" kind) and I made sure we use test-driven development with proper version control and CI. We have been trying to use Rust for some new projects but cross-compiling is still much more hit-and-miss with Rust (i.e. third-party libraries) than it is with C. I imagine it would be worse for proper embedded projects. |

But the language does bring benefits. In my experience modern strongly typed languages with large standard libraries and nice tooling are more productive than C (and probably more than C++, although writing idiomatic modern C++ is quite nice). C's simplicity is nice, but it still exists in a world where your only option for 3rd party libraries are zips downloaded from some random Sourceforge. Trying to write a C program with effective string handling is an absolute nightmare. All those things are solved many times over in other languages.
As a tool for writing very low level routines handling fixed length data, C is pretty good. But embedded development is moving away from that - every project seems to have some sort of web API, and that's when the downsides of C really start to show themselves.
