Longevity

Gandalf
Gandalf's temporal existence defies conventional measurement. As a Maia, his spirit predates the creation of Arda itself, placing his origins before the counting of years. His incarnated form in Middle-earth spans approximately two thousand years before his departure to Valinor. This combination of spiritual immortality and physical persistence represents a duration that renders human timescales essentially meaningless. He has witnessed the rise and fall of kingdoms, the forging and destruction of rings, and the passing of ages.
Social Media
Social media's existence spans approximately two decades in recognisable form, with platforms like Friendster (2002), MySpace (2003), and Facebook (2004) establishing the paradigm. Individual platforms demonstrate remarkable fragility, with once-dominant services declining into irrelevance within years. The broader concept persists through platform succession, yet no guarantee exists that current forms shall endure. In technological terms, social media remains an infant, its long-term survival entirely speculative.
VERDICT
Existence measured in millennia categorically surpasses twenty years of platform churn.
