Integrating VBA into excel was an interesting one as the excel team refused to just pull it in as a dynamic dependency but wanted it embedded straight into the deployment to avoid the DLL hell that was common on the windows platform. In addition going from having no automation via something like VBA to having automation required some pretty complex work. As for the Manhattan Project, you might want to think on the difference between the words complexity and difficulty. And then you might consider that when working with nuclear material to create the world's first nuclear bomb, you would want to keep the complexity as low as possible, sheerly out of self preservation.
