> 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?
Amazing how it doesn't even cross your mind that there are trade-offs to those choices. Green threads are awesome, but guess what, they come at a cost. Same for share-nothing semantics.
> 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!"?
You are again presupposing the BEAM has an absolute superiority over the JVM. "Better runtime" makes no sense on its own. Better is always relative to something. Better for whom? For what?
I'd bet that you work on a traditional CRUD enterprise software, and that IO(the database) is the real bottleneck of your app. In that case, sure, the BEAM is a solid choice(so is Python, Ruby and PHP nowadays). But let's please not pretend that is all there is to software engineering.
Any good reason for your rude tone? If we are going to invoke the what crossed somebody's mind trope, I'd lead with that when talking to you -- did it cross your mind to speak calmly and not assume something "did not cross" somebody's mind?
RE: your other similarly rude comment, I have not "appealed to authority" anywhere. I said that I have used multiple PLs / runtimes and made an informed choice... for me. I don't intend to add "...for me" after each sentence. It's redundant and obviously implied when it comes to tech because obviously people have made well-working prod systems with combinations of bash and Perl ages ago. So obviously people can make nearly everything work.
If you don't intend to discuss out of position of curiosity but want to jump on people then I am not interested.
Your first comment assumed I was "speed-running to a conclusion and squinting too hard", and this was "similar to the weird childish name-calling". I think that is in the same area(or worse) than saying "Amazing how X didn't even cross your mind". And sorry, but invoking that you have experience with X, Y, Z and thus your opinion is informed after criticizing some technology IS an appeal to authority.
> If you don't intend to discuss out of position of curiosity
I'm not the one making sweeping statements on the superiority of one piece of technology. Reading your other response, I think you are the one who have little to no curiosity in understanding how you might be wrong.
I have been on the other side as well i.e. the Java / JVM. Hence: "informed".
Your negative assumptions are tiring. Sorry that you got offended by what you quoted (and I said) but I'll drop here.
