You get problems like this, which you don't get in traditional OO languages: https://github.com/golang/go/issues/16474 https://github.com/golang/go/issues/16474

  What are you talking about? You could do exactly this in Java or C# or Python or Ruby or JS or etc. Not sure what ”traditional” languages you’re talking about, but this is just reflection and downcasting. It’s a bad idea, but it’s unrelated to OOP.

    You can't cast a type to an arbitrary interface and hope that it implements the method(s) you want to call in Java or C#.

      They aren’t “hoping it implements an interface”, they use reflection to determine whether or not the type implements the interface. This is pretty much the same thing in Java or C# with reflection and downcasting, but it’s a bad idea in both languages.
