#scala be like: oh no, ecosystem is too broken with many silos, 3 different effect libraries is too much, people can't decide, monads are too hard...
Scala solution: let's introduce a whole new thing called direct style, there's now 7 new libraries, competing against the previous 3 and std Futures. We are even working on effect things in a different way which will introduce 2 more ways to think about it!
Everybody else: yeah, tks but no, don't what deal with that craziness 😱😐
Martin Odersky's thoughts on "Lean Scala"

Lean Scala
Program code is for communicating between humans, not just for instructing computers. So we strive for code to be lean. Lean code is simple and understandable. It is as concise as possible without losing clarity.Martin Odersky (Language and Code)

Apache Pekko has left the incubator phase and is now a top-level project.

That's great news! Pekko was created as a Fork of Akka 2.6, right after Lightbend chose to pull a bait-and-switch by relicensing Akka to a non-FOSS license.
I have already switched to Pekko a few months ago, it went very smooth, and I am grateful to everybody involved in making this happen.

Contrarian viewpoint…
In #Scala, IO does not exist because of “fibers” (green threads). Ditto for Java's “reactive” libraries. That was just the marketing brochure. You could have lived w/ blocking I/O, given that Linux+JVM can handle 10s of thousands of threads (1:1).

Since other people are discussing these things, always a good reminder that on #scala using cats-effect library and using #FunctionalProgramming these thing are properly abstracted away nowadays and on daily usage one finally barely has to care at all about it. - https://typelevel.org/cats-effect/docs/thread-model
