I have written no less than 20 hobby mini-projects with Go but it's hardly an alternative to Rust. They serve fairly different purposes. Sure you can write almost any project X with either language but most of the time Go or Rust would be a bad fit for project X and a near-perfect fit for project Y.

What kind of projects that you can realistically be involved in, fit Rust but not Go?

Highly loaded network backbones come to mind. At one point almost every GC language starts to struggle.

I've written Rust services in financial companies and it maintained stable memory footprint and near-nonexistent higher P95 latency... for months without restarts.

Your second paragraph: I expect that this must be a microscopic part of their total source code footprint. Is the software used for (equity/futures/options) exchange connectivity? (Oh no, please don't tell me "crypto".) I cannot think of anything else that would warrant the investment in the 2020s.

		Depends what you mean by microscopic. If the entire project is a traffic forwarder, proxy, firewall-like, dispatcher / router etc. then that's the heart of the project and having the performance benefits of Rust there is absolutely crucial. It was not only crypto. We're also talking telecom nodes and there are a lot of different protocols and needs around them (I was surprised how many, and some telecoms are finally waking up to the 21st century and started utilizing proper containerization and virtual networks to enforce compartmentalization / isolation / security). On the broader topic: nowadays I default to Golang due to its better productivity and shorter dev iteration cycles, for what it's worth. However, there are projects where picking Golang over Rust would be irresponsible. Not the majority of all projects out there, absolutely, but there is an important subset that cannot be ignored. PERSONAL NOTE: Sadly most of us will never work on those, and I am trying hard lately to change that for myself. Sick of web dev, I started hating it so much that I can do it extremely efficiently and almost with my eyes closed but I still can't forever ignore my needs; we are creative creatures and forcing ourselves to be assembly line workers only leads to spiritual and mental health death.

I was thinking about this earlier today. I decided, albeit probably in a manner way too naiive... use Go if you want to write an app and use Rust if you want to write a program.

		I don't have your context so I'm not sure what you mean but in general, it's rather easy to write a web backend with Go, yes. And Rust is a very good fit for many types of servers.
