I like that he speaks from experience. If you new to F# it makes a lot of sense to shy away from exceptions, and in short examples result types could look very neat and nice especially in computation expressions. But in big codebases things can be very different. I would very much like to hear a criticism of this article / alternative view from someone who successfully uses result types instead of exceptions in reasonably big projects.
Nowadays there is a .NET Core, which is platform independent. And I think Microsoft is one of the main reasons why C# and tooling around it is as good as it is. So it is reasonable to say that $someBigCorp can be really good thing.
For those of you, who are new to Microsoft Universe, i would suggest taking a look at F#. While i think that C# is the best imperative language, F# will change the way you think about software development.
