If I were to travel back in time 4 years ago, and tell my old self that Haskell was starting to lose its shine, I wouldn’t believe it. I grew up on Haskell, my appetite for category theory was whetted by Haskell, my biggest programming projects have been in Haskell, and my dream job was to work at a company that used Haskell.
But now, I find myself simply not as excited about Haskell as I used to be. What changed?
