I'd personally rather see Haskell become part of the options for https://arrow.apache.org/, but this is still a cool project.
Looks like a pretty cool community building great tools with care. Using a functional language for data transforms sounds like a sane idea, haven't played around with it yet but it's definitely on my list now.
However they claim using Haskell for data science is "fast", which doesn't really mean anything until you have numbers to show. A little benchmark with pandas and polars wouldn't hurt I guess.
Haskell tends to be C-fast.
That's not what I see reported, they say Haskell tends to have bad memory layout generally and takes a 5x or so hit to performance.
Depends what you're doing, but it really can have C-comparable speed. [0]
Unoptimised/naive Haskell might be that slow. But that's true of a lot of languages and isn't particularly interesting to me. Java is slow if you do everything the naive way, too.

Java ain't slow even if you do really stupid stuff. Hell, I would even argue that java is the most resistant to stupid code. Some way over-abstracted everything linked data structure will be faster in java than it is in C.
Haskell's most badly optimised type, is the String.
Java's most badly optimised type, is the String.
Both of them need a string-builder pattern, the default operators don't work around things to do the right thing for you. They expect you to understand how data works.

Cool cool cool!
I still love Haskell, had dedicated several years to it while at the university. Was impossible to land a job with Haskell. Did some Scala but it’s in demise. F# and OCaml are extremely niche. Ever fewer opportunities and engineering management is convinced it’s impossible to hire functional programmers.
In this new AI-driven world, is there still place for such a luxury as functional programming?
I mean few people still code by hand, few read the generated code, models aren’t trained on functional languages, it’s inefficient token wise to use functional languages - while a lot become self-proclaimed software engineers overnight by just prompting LLMs.
there are a lot of strong claims here, but to just pick one:
where does that idea come from?
Hiring for Haskell is very easy, unless you need to hire more than 100 people on the spot, or don't offer remote. I've been doing Haskell hiring for 10 years, with more than 50 interviews, the applicants are always great, each time we had to pick the best of multiple candidates.
Cannot confirm functional programming being inefficient token-wise, or worse at being generated than other paradigms. Claude is great at Haskell.
The difficult parts about Haskell, such as understanding type checker error messages, are gone thanks to LLMs.
Type-safe, side-effect free code degrades correctness a lot less under heavy LLM action in my experience.
