There is still an unfathomably huge landscape of problems where C++ is the more mature, “right” choice over rust for new projects. Just from my (extremely limited and narrow) personal experience:
- scientific/numerical computing (super mature)
- domain-specific high performance computing (C++ is for better or worse extremely flexible)
- weird CUDA use cases (feels very native in C++)
- game dev as you mention
- probably much much more
C++ to me feels more like a meta-language where you go off to build your own kind of high performance DSL. Rust is much more rigid, which is probably a good thing for many “standard” use cases. But I’m sure there will always be a very very long tail of these niche projects where the flexibility comes in handy.
