(Author here) It's not about interfaces being an impediment but there being too many composition models, none of which seem to scale very well. A composition model is more than an interface. E.g. the way you compose a C program is you write the pieces (functions, structs) that are designed to fit together in certain ways, and then run the compiler which binds these together. The way you compose a web application is you invoke multiple processes that have a pre-shared notion of the protocols and they bind with each other. We're inventing model upon model, stacking them up like an wall of rocks. I'm saying we should look for models that are powerful but compact and can scale up. It should also be something that leads to less reimplementation because composition within it becomes easier. I don't think we have such models and I believe this needs deeper study.
