I worked with a shop that wanted to use Rust for their shiny new MVP. And they did... and yes we were not really good at training nor could prioritize/attract rust-experienced devs. The Lead rust dev left due to personal reasons and then we were left with a codebase nobody really had the knowledge/insights to support while rapidly iterating. We smiled and rewrote it in node.js.

I think devs get burned when the MVP turns into forever code and somehow are not given room to refactor/rewrite once validated... or they are surrounded by devs who are used to pain/bug-cycle and they (or the business) will accept doing things haphazardly as a cost of doing business. Fred Brook's Second-System effect comes to mind.

Ah ha! Rust! Now we HAVE to write good code because rust has so many protections!!
