I was thinking the same all throughout the reading. I've been using F# on GCP in production for 3 years now and it's fantastic and only getting better. You can leverage existing .NET libraries (for example, you get official GCP libraries from google) and if you use them enough it's easy enough to write a functional wrapper around them. I recently rewrote the frontend using Fable.React so that I can share code between backend and frontend.
