The problem isn't messiness. The problem is the additional mental load it creates for half of a household to keep increasingly more information in active memory while staying functional. If you continue this computing analogy, you can easily see how the added search cost, not to mention memory/storage load, dramatically affects system performance (but with the benefit of things being done with full contextual awareness). Compare this to a system with extremely limited working memory, which flies in comparison but only puts the very most recent or most critical actions in context. In a household with more than two people, especially, the resulting mental load can get unreasonable very quickly.
