So in a statically typed language, if all I know is that I'm getting a string as input, it'll force me to deal with all the possibilities. Is it a number in the form of a string? A null value? A string that isn't a number? The type system will guide me through handling all the possibilities and enforce that I handle all of them. With dynamic typing, there's always a chance you've missed a case and next time the data comes in it'll trigger an exception. If you have decent type inference there isn't extra typing and any time you think you're saving with dynamic languages gets eaten up having to manually fix things when errors happen at runtime. I'd much rather spend time fixing predictable compile time errors than unpredictable runtime errors.
