Besides a big target for Rust is the C and C++ world. On Hacker News in my experience you have a majority of commenters coming from the web world where no news in one year effectively means that the project is dead.
For us in the low level world "stable for 4 years" means "maybe we can start considering using it in production" and the lack of big buzz every other month is more a pro than a con. I'll take boring and reliable over shiny and breaks-every-other-year.
I've just started adding a new feature on a C project started in 2009. If I used Rust I'd want to know that my dev environment will still be usable in 2019. I think the commitment to stability will pay off eventually.
My personal intuition is that it will have become a strong alternative to C++ by then, and Go will probably eat the other side of that (at the 'upwards' frontier of C++, before/underneath e.g. Python), which given a decade could result in maybe 25-30% of major C++ projects moving or with plans to Rust/Go. That would be a healthy balance of alternatives, a true victory for these mid/low-level contenders.
It's not like the bottom of the stack can be won the likes of Python or Js at 80-90% within a decade. Structurally, it simply cannot.

10 years is a long time. Swift is 5 years old and it seems old and baked.
Considering the buzz Rust has had on HN, etc, I thought it was more popular.
Sounds to me like it needs some sort of push to get over a tipping point.
Often part of the problem isn’t technical. In business people don’t want to be first. Perhaps a few more high-profile users.
