As a c++ programmer, one of the great things about rust is that I no longer have to keep track of data ownership and management in head.
I can outsource this to the compiler and if I get it wrong the program won’t compile.
In c++ you still need to do all the same tracking and management if you want safe and correct programs, but you don’t get nearly as much help from the compiler if you make a mistake.
I think this is largely overblown if one uses modern C++. One of the things I do is stateful multi-threaded business servers and frankly comparatively to the overall project this "data ownership maintenance" is small to the point of being practically absent.
