Controversial opinion:
There are only 2 kinds of people that think Rust will not become a widely used language:
Those who don't bother to learn it, and only argue about it without any hands-on experience, and
those who don't understand which niche Rust tries to fill.
For me it was funny, btw. I started out as basically a Rust fanboy, back when the "First Edition of The Rust Book" was still just called "The Book"...
Then I learned a bit of Haskell, and was immediately disappointed that Rust doesn't offer the same convenience when it comes to working with Traits (cough Higher Kinded Types cough). So, while I never considered myself part of the first group, I definitely was part of the second for some time.
However, the more I've been trying to abuse Rust for stuff that would be better done in a higher level language (like Haskell), the better I understood why Rust doesn't offer those abstractions: They often can't be zero-cost, and using them in a language that tries to be very explicit about performance costs becomes very verbose... In other words, I learned the hard way what "systems programming" means in the case of Rust, and which languages it competes with, and which it doesn't.
