Out of curiosity: is posting internal company communications (referring to the e-mail here) on a public site like this legal? I'm not saying that it isn't; I genuinely don't know.
I've been writing small programs for fun in F# for the past couple of weeks. It's nice.
My main frustration with it is its lack of community. The Elixir forums are absolutely terrific; there is seemingly tons of knowledge sharing going on between passionate members of the community. The same with most other languages: if I Google how to solve a specific problem, an answer or an answer to an adjacent problem will pop up. That's true for Swift, Go, C#, Python...
It's not true for F#. F# seems to me almost like a dead language judging from the lack of relevant Google results, zero YouTube presence, no jobs where I live (northern Europe).
Is there a vibrant F# community somewhere online that I've missed?
I think the level of transparency on display here is really inspiring. I'd apply that same level of candor in a meeting with a peer or a higher-up and basically tell them that you are dissatisfied with the quality of the work that you deliver.
A good manager or colleague will be really receptive towards that kind of openness. They'll be able to help you cut through the "bs" so to speak and help you separate impostor syndrome noise from actionable facts.
