The nucleus sends mRNA to the ribosome. The ribosome makes proteins. Proteins do the work around the cell. Conclusion: Ribosomes are middle management.
Saying the Rough ER (Ducts with ribosomes) is responsible for the stuff it makes (proteins from ribosomes transported in a Smooth ER-like tube) is like crediting the inventor of the hot dog with inventing sausage and bread.
