I agree with you, I believe that simulators, games, software that are "walled-gardens" in the sense that they don't have a lot of interactions with the external world aside from IO and netcode for multiplayer games (that's a pita though), will be usually better in a purely functional model. We must either stay single-threaded or adopt purely functional programming or transactions in those kind of systems. Now, this can be achieved in both C++ and Rust as those kind of systems are not "safety critical", C++ has the edge in metaprogramming while Rust is one step forward in moving the lifetime correctness on the programmer's turf. It's hard to make a point which one is better suited right now as both in my opinion are flawed and have their advantages, it gets evangelical pretty fast. One thing I know is that C++ has the upperhand just because of the sheer amount of libraries that exist in the space and its supporters like Autocad, Valve, Epic and other companies that have billion $ infrastructure built on it.Right now I'm working with fax machines and I have to provide a C library which is consumed by Scala services. Neither C++ nor Rust would have been an advantage as we are familiar with other methods of verification which are more battletested.

People still use fax machines? What is the use case?
