Money
Money possesses extraordinary staying power. The concept has persisted for approximately five thousand years, evolving from commodity money through precious metals to fiat currency and digital tokens. Despite periodic collapses of specific currencies, the abstract concept of money shows no signs of obsolescence. Indeed, futurists predict some form of value exchange will persist as long as human civilisation endures, adapting to whatever form our species takes.
Shrek
Shrek faces the mortality that claims all cultural phenomena. While the character remains culturally relevant twenty-three years after his debut, no fictional creation has maintained peak relevance indefinitely. Mickey Mouse required corporate protection; Sherlock Holmes became public domain. Shrek's current meme-fuelled renaissance may represent a temporary resurgence rather than permanent cultural installation. The entropy of cultural memory claims all characters eventually.
