Why Haskell Is Making a Comeback in Production in 2026
from The Programming Languages Podcast with Fexingo: Python, Rust, JavaScript, and Modern Coding Hosted by Fexingo
Haskell has long been viewed as an academic curiosity, but in 2026 it's quietly powering production systems at places like GitHub, Meta, and a handful of fintech startups. Lucas and Luna explore how the language's strict type system and lazy evaluation are solving real-world problems around correctness and concurrency. They walk through a specific example: how a small trading firm used Haskell to eliminate an entire class of runtime errors in their order-matching engine. The hosts also discuss the trade-offs—steep learning curve, smaller ecosystem, hiring challenges—and why a growing number of teams are deciding the upfront cost is worth it. Plus, why a new generation of tooling (like the HLS language server and the GHC 9.8 release) is lowering the barrier to entry. This episode is for any developer who has wondered if pure functional programming is just a thought experiment or something you can actually ship to production. #Haskell #FunctionalProgramming #PureFunctional #GHC #HLS #TypeSystems #LazyEvaluation #Concurrency #Correctness #Fintech #GitHub #Meta #Production #ProgrammingLanguages #Technology #FexingoBusiness #BusinessPodcast #ModernCoding Keep every episode free: buymeacoffee.com/fexingo
