>Swift has clearly an advantage in that domain, as has C++, C#. In an enterprise setting such as Google no one actually wants speed and dynamism out of a language (C++ programmers are not allowed to use rtti for example), rather consistently boring, predictable, statically guaranteed results with as minimal fuzz as possible (Go, Java, C++) and enough competent programmers in that language.
That's a pretty weird statement, considering how hard it is to write a complex C++ program error free. I suppose Swift is much better in this regard - But compared to C++, Julia is a bliss and one can easily write huge applications error free, while I had my absolute worst debugging experiences in C++, where it's very easy to create obscure and hard to find bugs.
If you really need to get predictable results and actually know those results - you won't get away with a static type checker anyways, but will have to write & run tests, which then pretty much make it irrelevant whether your language is dynamic or not.
