My observation is most people who suggest Rust alternative don't use Rust. People who actually use Rust known it is worth to rewrite C/C++ software in Rust, either the whole or part by part. There is a tool to convert C source into Rust too so you can retain the whole functionalities while migrating to Rust. I have done this with Lua and it work wonderfully.
The good news is Linux now adopt Rust. In the end it will be all Rust although it may take a long time to migrate from C.
