iPhone
Apple supports iPhone models with software updates for approximately 5-6 years following release, after which devices enter a twilight zone of diminishing functionality. Hardware components, particularly batteries, degrade according to predictable lithium-ion decay curves, typically retaining 80% capacity after 500 charge cycles.
The oldest functional iPhone, released in 2007, is now a collector's item rather than a viable communication device. Planned obsolescence ensures that most devices are replaced within 3-4 years, generating a perpetual cycle of consumption and disposal that defines the consumer electronics industry.
Forest
Forests operate on temporal scales that reduce human lifespans to statistical noise. The oldest living tree, a Great Basin bristlecone pine named Methuselah, has survived for over 4,850 years, predating the Egyptian pyramids by several centuries. Forest ecosystems themselves have persisted through five mass extinction events.
The concept of ecological succession ensures forests regenerate even after catastrophic disturbance, given sufficient time and absence of human interference. A clear-cut woodland can return to mature forest within 100-200 years. The forest's upgrade cycle operates on millennia rather than fiscal quarters.
