Dynamic typing is fine for exploring. If I'm trying out a new API and don't want to look at the documentation every 30 seconds (or more realistically the documentation is terrible) then writing a simple service in Python is a great way to gain experience. Someone mentioned Julia; I think that most of the stuff you're going to be doing with Julia is exploring so it's fine that it's dynamic. But, for anything actually intended to be used, all the advantages of strong static typing come into play. The problem arises when people start out exploring a problem with a dynamic language, get something working, and then try to expand that dynamic program into something production-ready.
