alt Hacker News> That being said, has Akka started making full use of JVM's new green threads? Has Java itself started introducing immutability and STM / share-nothing as first-class citizens? If not, then by the "programmers reach for the defaults first" rule above I'd think Java is not yet ready.
> OK Clojure has these amazing libraries, kudos. Has anybody rolled up their sleeves and said "Alright, BEAM VM's reign is over, I am making the same or better runtime as them in Java / Clojure!"?
will akka use green threads? i'm sure it will when the developers behind it deem them useful.
will jvm add immutability, stm and share-nothing primitives that (i assume you allege) are missing? sure, i guess, when it becomes frequent enough ask.
you make it seem as if the world of software development is in some constant battle for supremacy, but it just isn't.
there is no "BEAM VM's reign". and if there was - it's unlikely that anybody would care to topple it. people just want to get their job done and they use whatever tools are available, familiar and convenient for them.
> I just don't want to deal with the endless pit of determinism bugs that global mutability nets us
and a lot of people agree with you. and there's a lot of tools that address that. and i can assure you, when working with clojure, even on the blasphemous mutable jvm runtime, that class of bugs is non-existent.
Well, I don't think you and I disagree on the premises, with the exception of you believing that I make some outrageous general claims -- which I did not.
> you make it seem as if the world of software development is in some constant battle for supremacy
I could have misinterpreted other people in the past -- very possible. But I also stopped caring about "battles for supremacy" a long time ago and at this point in life and career I simply use my experience and brain to go where my work is more productive, deterministic and fulfilling. To me immutability, share-nothing actors, strong vertical scalability (where a lot of PLs and runtimes do well, not only my favorites) and DX (like live prod REPLs and generally trivial observability) are those axii along which I thrive.
You and a few others seem to have emotional reactions to this which, I assure you, are very unnecessary. I ain't threatening neither your livelihood nor preferences.
