Sorbet: Stripe's Type Checker for Ruby
We discovered a bug in `srb init` for Ruby 3.1 recently that a teammate of mine is working on fixing at the moment. It's likely that if you tried again in a few days it'll have been fixed. Sorry about that, totally agree that the out-of-box experience should just work.
I wrote up an FAQ about the state of Ruby 3 and RBS here:
https://sorbet.org/docs/faq#when-ruby-3-gets-types-what-will...
The tl;dr is that RBI files (not RBS files) will probably always be the preferred way to declare types for third party code (because it will always support exactly the same set of features that Sorbet does). We have some people in the community look into teaching Sorbet to read the RBS format, but the existing parsers for RBS files are written in Ruby and are very slow, and there are some ambiguities in the spec that make writing a third party parser that compiles to native code tricky. You can see an attempt to write a fast RBS parser in C++ here[1], but again given that RBI files do everything we need them to right now and we have other features people are asking us for, we haven't prioritized RBS support incredibly highly.
Sorbet works completely fine without RBS files!

Open-Sourcing the Sorbet (Ruby) VS Code Extension
This article might help clear some things up:
https://sorbet.org/blog/2020/07/30/ruby-3-rbs-sorbet
tl;dr:
- RBS files are what Ruby 3 uses to describe types in separate files
- RBI files are what Sorbet uses to describe types in separate files
- Sorbet invented its RBI file syntax before RBS files existed. RBI files use the same syntax for types and signatures as in type annotations that live inside `*.rb` source code with Sorbet.
- We've been meaning to add support to Sorbet to consume both RBI files and RBS files, but we haven't had a chance to get around to it.
If someone beat us to it and implemented support for RBS files in Sorbet that would be amazing! Shopify took an early stab at implementing an RBS parser in C++ for performance[1], but I'm not sure what the status of it is today.

Sorbet Compiler: An experimental, ahead-of-time compiler for Ruby
(disclaimer: I work on the Sorbet team)
I think I understand GP's motivation: RBI files and RBS files are two different formats, and as a user of the language, people tend to want to use the officially blessed solution the language provides.
In case you weren't aware, parlour[1] is a popular open source project for working with RBI files. I believe it supports transparently converting between RBI files (Sorbet) and RBS files (Ruby 3).
There is also rbs_parser[2], a C++ parser for RBS files to convert them to RBI files, written by Shopify, a major user of Sorbet.
Stepping back: I haven't personally read many complaints from Sorbet users describing how the current state of RBI/RBS interop gets in the way of what they can actually do with Sorbet. Almost all the feature requests we get about Sorbet (both inside Stripe and outside) are for fixing bugs or implementing new language-level features. RBI files as implemented seem to work.
Sorbet already has an extensive set of RBI files covering the Ruby standard library (at least as good or better to my knowledge than any existing repository of types for RBS files), and there are plentiful tools for working with RBI files, listed here.[3]
If lack of first-party RBS support in Sorbet is holding you back from trying Sorbet, I'd strongly encourage you to give Sorbet a try anyways! Many people have shared great experiences adopting Sorbet in their Ruby codebases.

Ruby 3.3's YJIT: Faster While Using Less Memory
Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago.
If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly ruby-like in syntax, style, and developer ergonomics.[^2] Although it's an entirely different language. Also a tiny community.

What languages are useful for contribution to the GNOME project.
Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well.

Jets: The Ruby Serverless Framework
Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything.
My modern programming toolkit is basically golang + ruby + bash and I am never left wanting.
I do find Crystal (https://crystal-lang.org/) really interesting and am hoping it has its own "ruby on rails" moment that helps the language reach a tipping point in popularity. All the beauty of ruby with all of the speed of Go (and then some, it often compares favorably to languages like rust in benchmarks).
