I think I agree with you. When I was part of a growing F# team a number of years ago, everyone we hired was an enthusiast who just loved coding in F# and wanted an opportunity to do it professionally. It turned out that this love, combined with the constraints of the language, led to a super-clean and legible code base. The quality was (in my estimation) outstanding, and I was sad to leave it.

As an F# lover my heart sank at that "it turned out" at first. I'm glad someone got to live the dream somewhere haha

I'm at my current company (actually writing mostly typescript and node services now) because of a YC "who's hiring" post that mentioned F# positions (bait and switch /s, but my experience lined up heavily with the team I ended up joining which didn't use F#).

Sure, but that's a 'need' from programmers side - not from business side.
