I've personally seen this, it can be pure goddamn cancer.

The company hired a very smart charlatan and he convinced them to start a greenfield project in Haskell. Then they need to hire Haskell developers for this specific thing because everyone else only knows Java and Python. Nearly a year later they're barely getting started, but it's getting hyped like you couldn't believe. A lot of sprint planning time starts to become 'how do we start integrating [New thing]' because the Directors have been fluffing it so hard.

Anyway it never got used in prod. The development turned into a disaster and the original guy quit. The team got dismantled and the whole thing got memory-holed. Anyone in the org hearing the word "Haskell" would invariably just think about it lol

Not even sure these guys fit the standard mantle of language hyping charlatans. Most of the catastrophic choices were things you could do in any language. With the bonus of no meaningful comments and just committing to master so there's no PR comment history to help the future team's archeology project.
