For server-side web programming, what shall one adopt?
Python and Ruby are great dynamically-typed languages, with rich ecosystems, but don't have any type system. This makes maintenance, and evolution of the codebase, tricky in the long run.
For languages that do have type-systems: Go's is a bit too simplistic, while Java/Scala have robust type systems but are rather slow and don't hit the programmer workflow sweet spot.

There's no silver bullet around.
