Enterprise is very much a trailing indicator. On the whole Enterprise will adopt Rust the same way it adopted Version Control and the Internet, years late and reluctantly. Nobody making those decisions knows the first thing about technology, but that cuts both ways. It means there aren't going to be executives at Mondelez International chasing their software engineers to use Rust because it's a good idea, but it also means despite lobbying by C++ consultants, those executives don't care that an internal team started using Rust for a new project.

As to Game Development, well, one of the things Rust has been trying to do is avoid toxic people and if you wanted a concentrated supply of toxic people the video game industry is where you'd look. I expect there will be a lot of Rust in or near video games in the next decade, but I already pity the people working on them.
