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 really high coolness ratio for a language. The few jobs I do see in Scala are very cool looking. Very few boring looking jobs.
Scala is too complicated. Most scala code bases I have worked on have no enforced structure, the language allows for all sorts of unconventional programming paradigms
Yeah I love it when people start defining their own operators all over the place and give them all inscrutable names. "Dude just use the eggplant parm operator: <<=-=>>"
^ This meme is from 10+ years ago when Scala was at the peak of its hype driven by the FP craze. Nobody seriously writes cryptic-symbolic-operator code like that nowadays. Scalaz, the FP library most notorious for cryptic operator/method names, hasn't been relevant for many years. Today everyone uses Cats, ZIO, or plain Tapir or Play, all of which are quite ergonomic.
This is the type of thing that a good PR review culture will handle. I love that this is an option in some languages. But in a company, you need to decide what cool features should be used and when and how much.
Good PR review isn't really enough unless the organization is only large enough to handle around one PR at a time.
With languages like Scala I think its a clearer necessity that someone or some small group in an organization maintains a dominance of expertise or you have different groups that are only using the same language in name or facing overhead to keep in agreement where a lot of the best developers might be basically doing ambassador work.
This is exactly what turned me off. It supports so many paradigms that every line of code I wrote I had to sit and think if I was doing it the "right" way and it was miserable.
Part of that I think is the culture and not the language. Personally I try to use the least powerful method that gets the job done and that usually keeps me unblocked. In practice that usually means using it as a better Java and not going down the functional monad path. I know scala has gone through a rough patch and maybe migrating from 2 to 3 is painful. But if you try starting a new project now with the latest Scala 3, I think you'll find that its pretty nice. Even IDE support is pretty good.
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.
Scala's metaprogramming abilities coupled to a powerful type system are still unmatched. Among mainstream languages, only TypeScript gets somewhat close. For your typical service oriented architecture, libraries such as Tapir or ZIO HTTP are pretty nice. I haven't found anything as pleasant in other languages.
That said if an LLM can write 95% of your code today, this point is a bit moot, sadly.
It's not really moot though. The primary benefit of concise but robust frameworks like ZIO is that they are easy to read (like the program is mostly business logic with minimal syntax noise/programming language bookkeeping), not that they're easy to write (though that's true too). Metaprogramming also works nicely with LLMs because you get the expressiveness of something like Python (or better) while retaining a strong type checking layer to give a feedback loop to the LLM. In fact, it kind of shines with an LLM because you largely don't care if things like macros are ugly as long as they produce correct code to present to the typechecker/compiler, so it makes more sense to vibe code the metaprogramming layer to give yourself whatever you need to have straightforward business logic. Conciseness and direct encoding of business logic also helps to keep context focused.
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.
Here’s an emblematic example of the problems in the community - Scala Center’s executive director Darja Jovanovich berating a conference audience with sexualised slurs and swearing:
And instead of facing any consequences, it’s actually the whistleblower (John De Goes) who is criticised for calling her out.
This issue is rooted in politics (Darja is a political sciences graduate with no commercial or academic Scala experience - AKA a leftwing DEI hire, whereas John De Goes is a powerhouse contributor to the ecosystem who failed to bow down to the leftwing establishment that had installed itself in the ecosystem).
Scala’s downfall is the culture of writing libraries with the most esoteric syntax imaginable. It’s the opposite of Ruby’s “program with pleasure”—-it is “program with maximum cleverness” and “if it doesn’t look like an obscure math equation or symbol soup, it’s probably not idiomatic Scala.” Java’s designers were opposed to operator overloading due to potential for abuse, and did Scala deliver living proof/nightmare scenario of that.
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 ====.
I've onboarded experienced and inexperienced developers to fairly big Scala codebases for the best part of a decade and I can't think of a single time symbolic operators were brought up as a source of complexity of confusion. Sbt deprecated <++= 10 years ago.
Agreed. There was a period of time roughly 10-15 years ago where symbolic operators in Scala were very en vogue. That fell out of style in a big way and I haven't encountered symbol soup in a very long time.
Most of the conversations I have with folks about Scala issues these days center around implicits, tooling, and its decline/lack of popularity.
Jobs that you work on hard, complicated things. Scala is relatively popular in Fintech and Finance in general. There's things like Chisel or Spark. But there are relatively few simple CRUD app companies using Scala.
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.
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 "compiler plugin" which suggests to me that moving fully off scala 2 requires a meaningful redesign.
Chisel absolutely isn’t the type of software that benefits from upgrading because it’s largely standalone. They could be the last project still stuck on 2.x a decade from now and it wouldn’t make much of a difference to its users.
I’ve only used Chisel for a few projects but I’ve never used anything but Chisel in those codebases. Simulation, verification, and all the painful stuff in FPGA/ASIC development depends on non-Scala tooling and all of the inputs (parametrization) are just read in from JSON files produced by scripts in other languages.
It would be nice to be up to date but the hardware NRE is so damn high that working around any limitations in Scala support is a rounding error. Chisel’s outputs are sent out for $X00,000 fab production runs so no one gives a damn whether it’s Scala 2 or 3 as long as it ships a working IC. The last time I used Chisel I was working on a mixed signal design where the Synopsys Fusion Compiler (maybe Custom compiler?) licenses alone ran into the hundreds of thousands per year (iirc it was per seat, so we must have spent over a million per year on Synopsys alone).
I’m not super plugged into scala but I work with Spark quite a bit and my observation has been the whole scala 2.13 -> 3 transition is a huge mess for just about everyone who touches it. I don’t have enough hands-on context to understand why it’s so painful but it seems to be similar or worse to the python 2.7 -> 3 transition in terms of sticking friction.
It is a mess. I've spent some time trying to convert some academic oss projects and some removed features really force large redesigns.
I think rather than funding the stuff on this announcement, I wish they would fund a team of experts to work on migration of a prioritized list of projects. This would both provide example patterns of migrating substantial projects and unblock projects who have been saying "we would like to try migrating but library X we use still hasn't"
Well, a more optimistic take here is that if future development on the Scala language was funded explicitly by/for people who are current using Scala 2, that means that the developers would more clearly understand their requirements in terms of making an easier transition for users moving from Scala 2 -> 3
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 don't know what it looks like on the ground now, but Scala was the defacto language of data infrastructure across the post-Twitter world of SV late stage/growth startups. In large part, this was because these companies were populated by former members of the Twitter data team so it was familiar, but also because there was so much open source tooling at that point. ML teams largely wrote/write Python, product teams in JS/whatever backend language, but data teams -- outside of Google and the pre-Twitter firms -- usually wrote Scala for Spark, Scalding etc in the 2012-2022ish era.
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.
It wouldn't have to be used in very many places to justify a 377k investment. A few big European banks alone would be worth it. Their website says "we invest globally in the open software components that underpin Germany's and Europe's competitiveness and ability to innovate". The fact that Scala is used at a university could also be classified as innovation. This is a minor amount of money if you're going to compare it with a STEM or medical research grant.
Scala may have fallen out of favor but was quite popular few years ago. And perhaps still is the most popular EU-designed language (developed by EPFL).
For people who don't get this, EPFL is the Swiss Federal Technical Institue in Lausanne. Switzerland isn't part of the EU or EEA but has instead integrated itself with the EU very closely via a mindboggling number of bilateral agreements with the EU members and the Schengen agreement which allows for free, borderless movement. This has the effect of making it seem very much like they are part of the EU without actually being as such.
Chisel is very neat but "the number one language for building hardware"? VHDL and SV are the only things in this space that actually matter. Chisel is still a blip for now.
Hmm, I think we're talking about different kinds of "number one".
The ancestor comment called Scala "niche" and criticized the characterization of it as "widely used". So given that context, I was coming at this from a perspective of popularity; Chisel is orders of magnitude nicher than even Scala itself and orders of magnitude less widely used. Most of industry is still choosing VHDL or Verilog for most greenfield hardware projects.
I think you mean in terms of "best way to do it". Chisel can at least lay claim to that crown, sure, though I think you could say the same about Scala too.
(I might say Clash for hardware and Haskell for software, not that that does me any good.)
Is it niche? Scala is arguably the single most successful functional language. It interoperates with the whole JVM ecosystem. It's probably the #3 JVM language after Java and Kotlin.
Because the idea of classes is baked into JVM. So when writing inline code, with groovy, scala, kotlin, whatever else, the compiler has to basically insert fake classes into the jvm.
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.
This is nonsense. And, not that there's anything wrong with classes, but compilers no longer need to 'insert fake classes' for anonymous functions since Java 8.
You're being downvoted but you aren't necessarily wrong. Javascript is probably one of the most approachable functional-like languages without being dogmatically functional.
As a longtime Scala lover, I’m so happy to see this. Everyone in here hemming and hawing about version incompatibilities, build tooling and such conveniently forget the warts of other languages and their ecosystems. Scala is an incredible language, especially for the language being so flexible, which is a strength, not a weakness.
I am very happy for Scala. So many people taking the time to rant on it. Yes, you can do anything with Scala in a million different ways. So what? So can you do it in C++, Python, Rust, etc. I agree that the whole "Category Theory" libraries are way over the top, but so are libraries in Java using "factories" everywhere. Every language has its pros and cons.
More like 10. The Scala ecosystem was still really rough in 2011, remember how many companies got burnt trying to follow Twitter's footsteps (cf. the infamous Yammer testimony).
That's the problem with state investments in software. One can rightfully complain about misallocation of capital by private investors, but state investments are a whole new level.
Is it really accurate to call this an “investment”? The details are not known but it looks like a grant or donation by a charity rather than an investment?
I think that any time to expect to get some benefit from it, other than a nice feeling for helping out, it should not be called a donation, at least not a charity donation.
Happy to throw some of mine for that. Scala may not be as popular as some other languages, but it's relevant for use cases as diverse as those for which you would otherwise use Java/C#/Go, JS/TS, C/C++/Rust (via scala-jvm, scala-js and scala-native), and it's a very nice language to work with at that.
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.

yeah a small group of experts can leverage scala, its not a language for a corporate environment
That's sorta the curse of Lisps too.
Yeah sorta
I would say Clojure is a big exception to that - Clojure applications tend to be more uniform than even non lisps
This is exactly what turned me off. It supports so many paradigms that every line of code I wrote I had to sit and think if I was doing it the "right" way and it was miserable.

As a European project the foundation is likely pursuing funding from EU sources using the fact that it isn’t US tech as a selling point.

Others worth mentioning are Kotlin, Ada, Pascal, Haskell, Zig, Erlang, Elixir, Prolog, Ocaml.
PHP is also from Europe. Not sexy perhaps, but popular enough to mention.
Kotlin is from St Petersburg, it's even named after an island near it.
St. Petersburg is in Europe.
I thought what was worth mentioning was being European or not, rather than being part of an European legal entity or not.
How is Zig an EU language?
Sadly, I’m old enough to remember that Ada was the result of a US initiative to standardize a capable language for embedded development.
A good friend worked on the well regarded Telesoft compiler…
Former EU, there's Gleam.
[dead]
True to both. My brain not braining. Was thinking Europe-based/driven. Python started in CWI but PSF is USA-based.
Maybe they've applied for the grant 10 years ago when Scala was all rage
I made another comment about it. But the answer is Scala is the number one language for building hardware these days via Chisel.
https://www.chisel-lang.org/community
second link - 404
third link - achieved project on github
fourth link - educational project
Perhaps it's a very know and useful project, yet indeed seems very niche to me.
Chisel is very neat but "the number one language for building hardware"? VHDL and SV are the only things in this space that actually matter. Chisel is still a blip for now.
"...these days." Don't quote me out of context.
I genuinely don’t understand what you think “these days” means or how what I said was incompatible with it.
Ok, let's say you were going to start a brand new project today. What tech would you use?
Hmm, I think we're talking about different kinds of "number one".
The ancestor comment called Scala "niche" and criticized the characterization of it as "widely used". So given that context, I was coming at this from a perspective of popularity; Chisel is orders of magnitude nicher than even Scala itself and orders of magnitude less widely used.

Is it niche? Scala is arguably the single most successful functional language. It interoperates with the whole JVM ecosystem. It's probably the #3 JVM language after Java and Kotlin.
Spark is Scala, Twitter was (is?) Scala https://sysgears.com/articles/how-and-why-twitter-uses-scala...
Scala was niche (but of course, you need to define niche first) and its market share has shrunk further in the last decade.
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
Because the idea of classes is baked into JVM. So when writing inline code, with groovy, scala, kotlin, whatever else, the compiler has to basically insert fake classes into the jvm.
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.
This is nonsense. And, not that there's anything wrong with classes, but compilers no longer need to 'insert fake classes' for anonymous functions since Java 8.
There's also scala.js and Scala Native, even if the JVM is the primary platform.
> Scala is arguably the single most successful functional language.
That would be Javascript.
You're being downvoted but you aren't necessarily wrong. Javascript is probably one of the most approachable functional-like languages without being dogmatically functional.
Probably because it's an amazing language for people who know what they're doing

Happy to see investment in sbt and the stdlib
Sad to see code coverage tooling called out as something they’re spending money on
Happy to see scala get sponsorship
The lead maintainer of sbt does it as a labor of love. I am very curious if he actually will be receiving any money.
He won't: https://bsky.app/profile/eed3si9n.com/post/3mdgbjkg4ck23
I am very happy for Scala. So many people taking the time to rant on it. Yes, you can do anything with Scala in a million different ways. So what? So can you do it in C++, Python, Rust, etc. I agree that the whole "Category Theory" libraries are way over the top, but so are libraries in Java using "factories" everywhere. Every language has its pros and cons.
Very on brand for Germany to invest tech 15 years past its prime.
More like 10. The Scala ecosystem was still really rough in 2011, remember how many companies got burnt trying to follow Twitter's footsteps (cf. the infamous Yammer testimony).
This was a good joke. Surprised it got downvotes. Must be all the Germans who can't take a joke.
(In case you Germans still don't get it -- that was a joke, but feel free to downvote :) )
That's the problem with state investments in software. One can rightfully complain about misallocation of capital by private investors, but state investments are a whole new level.
The Albanian government invested 10M in Mira Murati's startup.
All on the basis of her...being Albanian.
Talk about public money mismanagement.
Is it really accurate to call this an “investment”? The details are not known but it looks like a grant or donation by a charity rather than an investment?
I think that any time to expect to get some benefit from it, other than a nice feeling for helping out, it should not be called a donation, at least not a charity donation.
What a waste of my taxes.
Happy to throw some of mine for that. Scala may not be as popular as some other languages, but it's relevant for use cases as diverse as those for which you would otherwise use Java/C#/Go, JS/TS, C/C++/Rust (via scala-jvm, scala-js and scala-native), and it's a very nice language to work with at that.
