>The other thing is that C# consistently adds features to itself that are inspired by F#, since F# already implements these features on the CLR, thus showing their viability. So what happens is that C# continually approaches a more bloated language with a subset of it being a poor copy of F#
C# and F# sometimes remind me another pair of languages: Java and Scala.
F# started out as integrating much better and being very selective of features, whereas Scala has been happy to add all sorts of features, to my understanding. F# has been feature complete for a while, mainly getting quality of life improvements and updating to maintain C# compatibility.
