Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Modern Java/JVM Build Practices
That has not much to do with the JVM. See Scala CLI[1] for instance, the developer experience is pretty similar to Cargo.
The thing is, with any non-trivial project, zero to hello world isn't a very useful metric. Gradle (and Maven, sbt, ...) do a lot more than Cargo, and their usage is primarily optimized for complex multi-modules projects.

No-GIL mode coming for Python
The new official Scala build tool / compiler front end (scala-cli) is amazing,
https://scala-cli.virtuslab.org/
The thing that really struck me after years of python is how it lets you out dependencies directly in a comment on top of a script and it will download and run with them automatically, without poisoning any system settings. It's so simple!

I had a great experience with Scala and hopefully it will get more popular
sbt can indeed be a bit harsh for beginners. If your aim is not to build a big project, you might want to use scala-cli instead : no complex build script, only command line goodness to run, test, compile and package your code. Yes it supports dockerization. No need for a dockerfile.

Hermetic Java: Self Contained Executable Images
Imo the tooling has to become way more user friendly. The Scala community has picked up on this and made Scala-CLI the official running tool for Scala. It's a great tool for single module projects and makes everything from adding dependencies to building fat jars very easy, also the runner comes as a native image. The reason I'm mentioning is because sometimes we forget how hard it can be as a beginner, especially when younger people are used to simpler CLIs from newer languages.

[NEWBIE] Why were `~/project/` and `~/target/` added after running `cs setup`?
Check out Scala CLI as it will very soon be the one true and sanctioned way to get started.

scala has 2 healthy and pretty complete lib ecosystems : check out typelevel and ZIO. Both are FP oriented, which might not be your cup of tea at first glance but I would encourage you to try em out ! Softest introduction would be to start with the typelevel cats library and build up from there. The excellent Scala with Cats will ease you softly into an FP mindset. It's a bit dated and for scala 2 only but translating to Scala 3 is a very good exercise if you feel so inclined !

Is it prudent to use Scala for anything new?
Last but not least, Scala is currently the language with one of the best effect systems in my opinion (https://zio.dev/). Kotlin for example has copied the approach with https://arrow-kt.io/ which I think is great actually. But when comparing Scala and Kotlin here, Scala wins by a large margin, it is a completely different world. It's like building a highly concurrent system in Erlang vs C.
Of course, if you don't want to learn things like union types, traits/typeclasses and effects (similar to async/await but more powerful) you will be annoyed by Scala. But once you learned them, you can never go back.

Is Parallel Programming Hard, and, If So, What Can You Do About It? [pdf]
I use ZIO (http://zio.dev) for Scala which makes parallel programming trivial.
Wraps different styles of asynchronicity e.g. callbacks, futures, fibers into one coherent model. And has excellent resource management so you can be sure that when you are forking a task that it will always clean up after itself.
Have yet to see anything that comes close whilst still being practical i.e. you can leverage the very large ecosystem of Java libraries.

40x Faster! We rewrote our project with Rust!
The one advantage Rust has over Scala is that it detects data races at compile time, and that's a big time saver if you use low level thread synchronization. However, if you write pure FP code with ZIO or Cats Effect that's basically a non-issue anyway.
