The article mentions that you can leave types aside for a moment, when you want to rapidly develop something.
That's the worst programming advice ever.
Good design starts from typing.
This is my feeling too, you will spend longer debugging and much longer supporting any significant sized project. However we must acknowledge that many people have an opposing view, that totally dynamically typed languages can speed up the total cycle not just initial writing.
