iPhone
The average iPhone maintains functional operation for approximately 4-5 years before battery degradation, software obsolescence, or physical damage renders it impractical. Apple's engineering employs aerospace-grade aluminium and Ceramic Shield glass, yet these materials offer limited protection against the accumulation of entropy.
The device's lithium-ion battery loses approximately 20% capacity after 500 charge cycles, creating an inherent expiration date regardless of external care. Furthermore, the rapid pace of software development ensures that functional hardware becomes effectively obsolete long before physical failure occurs.
Boat
Well-maintained wooden vessels have demonstrated operational lifespans exceeding 150 years, with the Star of India, built in 1863, remaining seaworthy today. Modern fibreglass and steel construction extends potential longevity further still, with proper maintenance enabling indefinite operational continuation.
The boat's durability derives from its modular construction philosophy—individual components may be replaced whilst the essential vessel persists. A boat's hull, decking, rigging, and engine may all be renewed without losing the fundamental identity of the craft. This capacity for continuous renewal represents a form of practical immortality unavailable to sealed electronic devices.
