Abstractions and metadata are the future of architecture in systems engineering, as they were before in software engineering. In many languages, there are abstractions and metadata; however, systems engineering has never adopted this view. Systems were always thought of as too unique for any standard abstractions. Now that we’ve standardized the lower-level abstractions, we’re ready to build new system-level abstractions.
