Wading in here a little bit, and I know you've thought about this --- I think it's reasonable to say that there are problem domains where it's a very good thing, and problem domains where it isn't.
I think a subtextual problem for Rust advocacy is that the places where it's a clear win are a small subset of all software problems, and that space is shrinking. Rust would, in that view of the world, be a victim of its success: it's the best replacement we have for C/C++ today, but the industry has moved sharply away from solving problems that way, and sharply towards solving them with Javascript.

(Deno is doing something smart here.)
