Except that you miss a very important point - nobody cares about the stuff you listed. I build models and use shiny to create a front end for clients to interact with them. They are very happy and pay me very handsomely. I can assure you that this is the case across the board. R is for analysts, not for programmers. It seems like programmers feel intimidated, because analysts now code their solutions themselves.
