Absolutely right. However, it's not good to replace too much manual labor, either. There is also a balance between too much and too little (i.e. not learning enough manual skills to take care of yourself).
There is a balance in both the mental and physical domains. Those who have a high intellectual capacity will probably think otherwise because intellectual activities is what THEY like to do. But the truth is, some people enjoy manual labor and it's not good to completely replace them either because there is art in manual work as well.
