Dog
Dog maintenance constitutes a significant ongoing commitment. The creature requires daily feeding, regular exercise, periodic veterinary attention, and continuous management of its excretory functions. Grooming needs vary by breed but may involve substantial investment in brushes, clippers, and professional services. The dog must also be considered when planning travel, requiring either companion-friendly accommodation or the arrangement of alternative care. These responsibilities persist for twelve to fifteen years on average.
The Internet
Internet maintenance for the typical user involves relatively minimal direct intervention. Monthly subscription payments enable automatic service delivery. Equipment requires occasional replacement but generally operates without attention. The primary maintenance burden falls upon engineers and administrators operating at scales invisible to domestic users. One simply pays the bill, restarts the router when instructed, and enjoys the service. The system maintains itself through distributed infrastructure.
