(Note that that's an absolute.) :) Anyway, I'm not trying to argue that types are not useful, they are. What I'm saying is that Python's loose approach to typing is useful "in the small" so to speak, but as projects grow larger you want "harder" types, checked by machine. Same thing with DB schema: No-SQL only makes sense in the small domains where the schema can be ignored or treated as an afterthought. Above a certain size and you grow a schema again and might as well do it right.
