> If that's true, how do you explain the observable pattern of many consumer applications degrading in UI functionality and coherence after a certain point?

Most consumer software in developed under the assumption that features only have a cost when being built. Their maintenance cost, and the combinatorial complexity each new feature adds, is barely considered. As a result, software teams add complexity at a speed that exceeds the rate at which the team's size, and the volume of work it can handle, grows. Eventually this reaches a critical threshold and the quality of the software starts to decline. But this doesn't mean the software couldn't still be improved, just that there isn't the resource available to do so.
