Within the tiny set of scenarios where Rust is applicable as of now, isn't it completely dominating?

It's dominating in hype and excitement for toy and pet projects. This is just the first few steps. Too few people have dabbled enough yet.

The next step is enough stability/maturity that more open source and maybe fang infrastructure can use it. And when the reasoning behind this becomes widely digested, most "green field" projects will choose Rust.

But that may be ten years away?
