Agree it is mostly computerised. Todays aircraft are far more technical and forgiving when loads / weights are not spot on. Routes and loads are repetative so the load / balance / loadplan might be the same today, tomorrow and three years from now. I think what you are saying is common to the complete familly within aviation. All of us are gradually down skilling and earning less, the magic has long gone as have the rewards. However, is this not happening in the majority of jobs / tasks worldwide not helped by the present climate.
