iPhone
The iPhone demonstrates remarkable adaptability through its software ecosystem. With over 2.2 million applications available, the device transforms from camera to calculator, from navigation system to musical instrument, based entirely on user requirements.
Regular software updates extend device capability beyond original specifications. The same hardware that shipped in 2020 gains new features through iOS updates, demonstrating adaptability that purely physical entities cannot match. The iPhone's digital plasticity enables continuous evolution without physical modification.
Marathon
The marathon's adaptability manifests through its universal accessibility. The race requires no proprietary technology, no operating system, and no network connectivity. Whether run on the streets of Tokyo or the plains of Kenya, across desert or through tunnels, the marathon adapts to virtually any terrain capable of supporting human locomotion.
Crucially, the marathon adapts to the runner rather than demanding the runner adapt to it. Wheelchair divisions, visual impairment categories, and age-graded scoring systems ensure participation regardless of physical circumstance. The marathon's 42.195-kilometre distance remains constant whilst accommodating infinite variation in approach and achievement.
