I disagree with the speed of an interpreted language. Ruby and Python (to a lesser extent) make writing flexible, readable code very, very easy. You don’t have to worry about types (unless you want to) and correctness; there are lots of ways of getting things done in those languages, and writing tests/mocks/stubs is WAY easier because of that.
In my experience, what would take me 30 lines of Ruby with maybe the same number of lines for its test takes 2x the length and boilerplate with Golang.
