That’s a reductive way of talking about a group of people. Is that from your personal experience with Haskell fans?

My personal experience with Haskell fans doesn’t match that at all. The Haskell fans I meet tend to be reasonably pragmatic, but care more about correctness. There are some who do research, but they acknowledge that research doesn’t always yield practical advancements. The Haskell fans I know will acknowledge that Haskell is not most people’s first choice for a language, and that one of the main benefits of Haskell is to yield insights that can be ported to other languages.
