Why would the governments invest money on such a niche language? "Scala is widely used to build and operate essential systems across multiple industries." - very bold statement.
I made another comment about it. But the answer is Scala is the number one language for building hardware these days via Chisel.
Scala isn't as hot as it used to be. I think the rough Scala 2->3 transition, coupled with improvements in the base Java language, emergence of Kotlin + Android support, and popularity of Python in data science and data pipelines (lets just do everything in one language became popular) kind of made Scala not quite as popular as it could have been. Plus the long compile times are a pain. However it seems to have a rea…

You got it. Scala had a shot being an early mover in the JVM functional programming space, but they really shot themselves in the foot with their version transition problems and tooling issues you allude to. Java is probably "good enough" for most shops now, and if you are not bound to the JVM I really don't understand why you would go with Scala today.
Scala's decline started before Scala 3, which brought its share of breakage (sometimes for dubious reasons, like the new syntax) but also fixed many warts. Tooling has improved a lot lately, but it's too late. > if you are not bound to the JVM I really don't understand why you would go with Scala today.

I learned recently that one of the killer apps for Scala seems to be in hardware design. Chisel [0] is the core technology of the best open source RISC-V chips. Chipyard [1] is designing leading edge type OOE and AI chips and all of the code is written in Scala. Personally, I can't wait for some of these designs to start being mass produced and put in laptops and phones. [0] https://en.wikipedia.org/wiki/Chisel_(prog…
So, as a justification for support of scala, the thing that seems lacking to me is that Chisel seems to still be centered around scala 2? E.g. their recommended template for getting started still uses scala 2 ... so without support to motivate them to use scala 3, it's not obvious that Chisel benefits much from current work on the scala language? I have not fully understood the Chisel project but I see they have a "c…

Anything that runs on JVM should not be invested in.
Why? I bet you never even wrote custom VM for your lang/architecture. There are like dozen of implementations for JVM alone: sun, Oracle, gnu, IBM etc etc
This may seem trivial, but because its fundamentally "hacky" its not something that is ever going to be as easy to work with and expand.

Really this is all true with humans too, but IMO it's multiplied with LLMs because they are insanely capable at dealing with the guts of metaprogramming wizardry if they need to, so you don't end up in a world where that one guy that understands it leaves and then no one can possibly maintain it.

I worked in Scala for most of my career and it was never hard to get a job on a growth stage data team or, indeed, in finance/data-intensive industries. I'm still shocked at how the language/community managed to throw away the position they had achieved. At first I was equally shocked to see the Saudi Sovereign Wealth fund investing in the language, but then realized it was just 300k from the EU and everything made sense.
It's still my favorite language for getting things done so I wouldn't be upset with a comeback for the language, but I certainly don't expect it at this point.

Now I still want operator overloading, because I favor enabling instead of disabling approaches, and I want, for example, new numeric types to have natural syntax that blends in with built-ins, or an equality operator that works consistently. I’ll even settle for += append to strings and collections.
But even Scala standard libraries take operator use to wild extremes. Apparently it’s not enough to use + to append collections, you must use ++. Except Vec you can add with +. There’s ++= and ++=:, and /: and :: and ::: and ?^ and ?^.
Spark Scala interface introduces =!= for inequality comparison. There’s |@| from Cons library. Don’t get me started on Akka. SBT introduces Surprisingly you can’t override ==, so Spark implements ===. And specs2 testing library implements ====.
Very on brand for Germany to invest tech 15 years past its prime.
(In case you Germans still don't get it -- that was a joke, but feel free to downvote :) )
