The concept of a data-mesh is more of a business concept as opposed to tech. IMHO the idea being proposed is that of a conceptual data-server (not to be confused with database server) much like a HTTP server / Mail Server where people can engage with data as a first class citizen and create "data" products. This is especially true as we move from HTML to somewhat HDML (Hyper data markup).

By making data as the product (abstracting all the gory details), you are fundamentally engaging with data through a UI or an API. As you expose these products they become accretive while fundamentally encapsulating the domain expertise within them.
