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 Async Primitives on iOS, Android, and the Web
Kotlin also has a construct for asynchronous collections/streams. Kotlin's version of AsyncSequence is called a Flow. Just as Swift's AsyncSequence builds upon prior experience with RxSwift and Combine, Kotlin's Flow APIs build upon earlier stream/collection APIs in the JVM ecosystem: Java's RxJava, Java8 Streams, Project Reactor, and Scala's Akka.

What are the current hot topics in type theory and static analysis?
First-class distributed and multicore computing. Swift has first-class “actors” and “distributed” methods. Unison, Erlang, and Elixir are built with distributed being one of the #1 concerns. Though first-class is not super common and I don't really expect it to be because usually libraries are enough (e.g. Scala has Akka and is used WIDELY for distributed); whereas something like linear types and typed effects, you can't emulate in a library.

Anything close beam/otp for other languages?
Akka is a library that implements the actor model for JVM languages. Mainly in Scala, but you can use it in Java too, and maybe others. It doesn't feel as ergonomic as Elixir, but if Elixir is too "out there" for the decision makers in your case, this might be a friendlier alternative.

About Elixir and the microservices architecture
Note Akka, the Java & friends framework, is working with the actor model and have as main inspiration Erlang to mimic some features of the BEAM on top of the JVM.

Akka will no longer be Open Source
If I hear about Actor model, the first thing that comes to my mind is the popular Open Source library Akka.
Lightbend, the company owning Akka, recently shared a blog post signed by the CEO announcing a license change from Apache 2.0 to Business Source License 1.1, a proprietary license. You can already find it in this PR, merged a couple days ago.

Why We Are Changing the License for Akka
Akka 2.6 is on the open source Apache license, that is unchanged (its not possible for Lightbend to change an existing license). Its only the new Akka 2.7 which has the BSL license, so as long as you don't upgrade you are fine. See https://github.com/akka/akka/pull/31561.

We Are Changing the License for Akka
Here is Akka's dependency specification: https://github.com/akka/akka/blob/main/project/Dependencies....
How many of these would have to opt for this source available approach before Akka would no longer be sustainable?
I don't think that the Akka change is aimed at cloud providers. Akka is a toolkit for building highly concurrent, distributed, and resilient message-driven applications for Java and Scala [1]. It's not possible for AWS to offer their own "Akka service" the way they offered Redis through ElastiCache. This change affects companies that build software using Akka, many of which may not be software-focused. For example, here's a case study of an oilfield services company that uses Akka:
