Scarf has moved away from Haskell

Scarf, a company that built big parts of its business on Haskell, has now publicly said it’s moving away from the language — and the internet immediately turned it into a messy family argument. The company’s founder made it clear this wasn’t a casual fling gone wrong: he’s been a Haskell believer for 16 years, helped lead parts of the community, and says the language delivered real reliability in production. But in the age of AI code helpers, he argues, long build times and setup pain now feel like a dealbreaker. In plain English: if an AI can spit out code in minutes, waiting ages for the computer to check it starts to feel unbearable.

And wow, the comments did not quietly nod along. One camp basically yelled, “Are you kidding? AI makes strong guardrails more important, not less,” with several people saying they trust stricter languages because AI often produces junk. Another camp mocked the whole thing as a glorified “vibecoding” confession — a spicy way of saying Scarf wants to let AI guess its way through coding faster, even if the code is sloppier. Others zoomed out and wondered if we’re entering a “post-language world,” where the best tool is simply the one that’s fastest for both humans and bots. Meanwhile, some readers were baffled by the move toward Python, arguing it’s exactly the kind of language AI makes look worse, not better. In short: one company changed tools, and the community reacted like someone announced the breakup at Thanksgiving.
