yes, I am not arguing for a single language. But many of the domains you mention are actually intrinsically similar once you map them to the underlying information flows. This explains for example the extreme ubiquity and longevity of things like relational databases and SQL. There are several genuine and orthogonal domain "dimensions", e.g real time systems or parallel processing etc, but I would say that is a handful, not the multiple dozens even hundreds of idioms we use to program digital devices...
