I don't care about any of these three languages. I will never need to learn them because they are not used in the real world of today's tech stacks.

Please don't do programming language flamewars here. They're tedious and can destroy a community.

Okay, I'll leave you and your Echo chamber.

I think there's room for debating whether this sites fetish for new programming languages correlates to the real world. I put forth that perhaps it does not, and you're free to disagree.

Flagging me as a troll because you don't like my opinion seems a bit much

No one flagged you as a troll. But the kind of discussion you were starting here is extremely tedious—it has been repeated a million times and provokes people into making dumber and nastier posts. Surely it's not hard to understand why we don't want that here?

Maybe, but our company uses services from at least three companies that use elixir: Divvy, Slab, and Pagerduty. Discord uses elixir. And Whatsapp famously uses erlang. But I suppose those companies are fictional.

So Stripe, Discord and Whatsapp don't count as real world?

Don’t restrict yourself to real world tech stacks! Regardless of wether these are or are not used by large companies, playing with different languages teaches you stuff to improve how you write your own.

Yes but then you're perpetually depressed when you realize what you have to use day-to-day :P

Don’t be! I’ve been using Haskell at work for the last year, but recently I discovered how much easier it is to use Java/Scala because of all the great libraries. Grass is always greener :)

Scala is probably the most expressive statically typed language around, so I personally wouldn't feel bummed about having to use it. Java on the other hand...

Does Scala see much use out of the big data niche nowadays? I've considered picking it up, but I'm always discouraged by someone telling me to use Kotlin instead, or stories of companies abandoning Scala for reasons like complexity and on-boarding.

Honestly I thought this about Java because people told me they thought this about Java, but once you try work with a language lacking libraries you need it’s a lot more appealing! Also I found things like Akka and JML make it even fun to write.

Do you have significant experience with Java?

Because I shared your views until I started working with it at a good team :-)

As I continued writing botj Java as well as other projects on other stacks Java became less and less annoying until today it is one of my two favorites.

I probably wouldn't mind working with modern java with a good team, but I don't like my odds.

Scala's type system is more expressive than Haskell's? I didn't know that. What makes it more expressive?

Subtyping, of course.

Not depressed at all. Python makes me happy
