Game industry is solidly C++ and that’s not changing anytime soon.

It’s not just inertia. Games have very specific latency and timing requirements that required tightly integrated language and compiler features developed for this very purpose. The financial industry too has similar needs and solutions. Rust isn’t a fit for those use cases. Not without a mountain of work that no one is doing, nor would be likely to be accepted as it conflicts with the design goals of Rust.
