Death of a Programming Language Dilettante

This isn't really about programming languages, as much as picking the right tool for the job.

My dream world at this point: Rust everywhere. Frontend, backend, middle tier, microservices, etc. It has the potential to be all those things. Will it happen? Will it overcome the behemoth that is JavaScript when WebAssembly is finalized and in all browsers? Will it fend off Swift as that language is ported to more platforms? Will it start to supplant the core which is C?

I want it too, but who knows. Right now I have to work in JavaScript, Python, and Java for work, with some Ruby for automation. That's real life.

It really seems we are in a world of infinite new programming languages. Typically in my career there was always a "common" language and the Next Best Thing. In the 1980s Pascal was common but C was touted as better, then in the 1990s, C++ replacing C, then in the early 2000s C++ was common and Java was the next best thing. But now with Rust, Haskell, Clojure, Swift, Go, etc. etc., it really isn't clear what the Next Best Thing is.
