iPhone
Individual iPhone models receive software support for approximately five to seven years, after which they transition from cutting-edge technology to electronic archaeology. Battery chemistry ensures gradual performance degradation regardless of software status. The typical device lifecycle spans three to four years before users succumb to the allure of newer models with incrementally improved cameras.
Apple has sold over 2.3 billion iPhones since 2007, yet virtually none remain in active use from the original generation. The device exists in permanent planned obsolescence, each unit designed to become inadequate precisely as its successor arrives in carefully orchestrated retail theatrics.
Mount Everest
Mount Everest has maintained its general configuration for approximately fifty million years, with the summit reaching its current approximate height roughly three million years ago. Geological projections suggest the mountain will continue standing for millions of years hence, gradually eroding at rates imperceptible to organisms with lifespans measured in decades.
The mountain has witnessed the entire arc of human evolution, from early hominids gazing at distant peaks to modern tourists photographing the summit with devices that will be obsolete before they return home. Everest will likely outlast not merely the iPhone but the entire concept of consumer electronics, remaining long after humanity has either achieved interstellar colonisation or succumbed to various self-inflicted catastrophes.
