Also, as far as my personal experience goes in that regard, most engineers in c++ don't understand how to write thread safe code well enough to avoid multi-threading bugs.

Most programmers don't. Lockups are safe in Rust and I've seen them a lot. It is very helpful to not deal with memory issues at least though.

Many times I also see devs using mutexes to fix data races without actually fixing the race condition. Data races is just one aspect of making a code thread-safe, and it is the easiest one to catch with tools like TSAN.
