A needlessly confrontational view. Some people do use dynamic typing as a way to stumble around until it works (e.g. most scientists) but some others simply don't want the noise associated with a static type system accurate enough to really say what you want; especially during prototyping/interactive use. Which is why gradual typing exists, really.

Same reason my views about GC evolved from "it's for people lacking rigour" to "that's true, but there's a second benefit: no interleaving of memory handling and business logic to hurt clarity".
