From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yes, it's because it keeps track on object lifetimes and data access when sharing objects, even across threads. It means that once things compiles a whole category of common and often difficult to debug errors are gone. It means much less time debugging and fewer issues once in the hands of the end user. There can still be bugs but it's more about logical errors than difficult memory issues.
As a C++ dev for 20 years, I love Rust. Humans are fallible, even if endeavouring to use safe patterns. Might as well just let the compiler use some CPU cycles on that.
I think new projects in Rust make sense but my - uninformed - opinion is that we should be wary about porting old C/C++ software due to those other classes of bugs you mentioned. The logical type errors I see at work and in open source projects using memory safe languages can be fiendish in their own way.
