Rust is not boring technology. There's too much ecosystem churn, and new language features are deployed too often.
C++ isn't boring technology, either. If you just want to deliver value, I'd recommend Java.

In my experience, Rust delivers by far the fewest number of bugs in production out of any mainstream language. It gets the fundamentals right like nothing before it. &, &mut, Send and Sync take care of many classes of bugs in the inner loop of productivity.
That kinda feels like saying Linux is too crazy because new apps get made for Linux frequently.
You can use the same part of the language tomorrow that you used today. Nothing is changing out from under you. If you're afraid of libraries, don't use them. You'd have the same problem in any ecosystem that is new, no?
Apps are okay, but other parts of userland that roll out breaking changes on a regular basis are definitely a problem [1] [2] [3]. Even if they aren't technically part of the kernel, they are usually used with it to provide a complete working system, and they break stuff all the time.

Not much of an issue if you stick to the stable subset of the language, and libraries that work within that subset.
