Well, I was just comparing Java - a complied, strictly typed languages to another in the same domain - Go. Scripting and interpreted languages like python, ruby are a different thing altogether. I agree with you that ruby/rails or python/django get it done a lot faster. On the JVM, we get close but not quite - with Grails and Play. Spring Boot seems to be getting up there as well in terms of productivity. They still have some way to go.
