Episode 78 of The Programming Languages Podcast explores Haskell's unexpected resurgence in production environments. Lucas and Luna break down why companies like GitHub, JPMorgan Chase, and a European airline are adopting this purely functional language for critical systems. We focus on the concrete case of a legacy Spark pipeline at a major bank being rewritten in Haskell — cutting infrastructure costs by 40% and eliminating runtime exceptions. We discuss how Haskell's strong type system, laziness, and purity reduce debugging time and enable safer concurrency. We also touch on the rise of the Haskell IDE, GHC 9.12's performance improvements, and the growing adoption in fintech, healthcare, and blockchain. No theoretical jargon — just the real reasons developers are giving Haskell a second look in 2026. #Haskell #FunctionalProgramming #StrongTyping #ProgrammingLanguages #SoftwareEngineering #Fintech #JPMorgan #GitHub #GHC #TypeSafety #Concurrency #ProductionCode #Technology #Podcast #FexingoBusiness #BusinessPodcast #TechPodcast #CodeCraft Keep every episode free: buymeacoffee.com/fexingo
