don't get me wrong - i want F# features in C#! I like the ecosystem and both languages.
I'm just pointing out that no matter how cool the language is if it doesn't serve business needs(hiring, onboarding ,ease of replacing staff, target market) it won't be picked.
I've worked with a lot of junior devs/graduates on a large F# project, in that context hiring/onboarding for F# hasn't at all been a limiting factor. Ultimately F# is not a particularly difficult language to learn.
