Hard to predict what the "Future" is.

Rust fills a niche. It's not the answer to everything.

The learning curve is steep, and for many applications, the benefits are nonexistent.

Although you can use Rust (or anything, even Bash if that's your thing) to write web applications, Ruby, Python, PHP and Javascript are far more productive and this is not going to change tomorrow.

Rust's borrow checker doesn't add anything besides complexity here.

Go is also a nice balance between being simple to use and powerful as a system language (unless "has no GC" is how you define a system language).

Swift has most of the best parts from the language above.

Crystal is a pleasure to write and runs fast.

Zig may eventually get more traction.

Something like Rust, but accessible, readable, that compiles quickly, is stable and has a natural way to do async operations could quickly make Rust obsolete.
