>Rust is mainstream For sure it depends what you mean by mainstream. If a FAANG uses language X, it's language X mainstream?

I'd venture to say that to be considered mainstream a language has to at least pass 1% threshold in Tiobe index (or the equivalent in Redmonk or others).

If Rust is mainstream, then Fortran is über mainstream

I would argue that Fortran _is_ "über mainstream" - if you look at computing as a whole. It may not be used extensively for CRUD applications, but it is part of the bedrock of basically all computing. And there are some niches where it is the main/only language.

Rust will likely end up in a similar place - enormously useful in its niche, foundational for infrastructure outside, and with enough uptake and stability to make a career out of. I don't think anyone expects it to eclipse popular dynamic languages for web development, but it might make inroads on C and C++ in areas where active development is still needed.

The rankings in that index are highly suspect. It has Visual Basic at #6 and Classic Visual Basic as #11. Meanwhile Kotlin is down in position #38 and TypeScript at #46 beneath COBOL, PROLOG, Scratch and Logo!

(And FWIW Rust is #26)
