Elephant
The African elephant lineage has persisted for approximately 5 million years, demonstrating remarkable evolutionary durability. Individual specimens routinely achieve lifespans of 60-70 years, during which their memory systems require no maintenance, replacement, or scheduled downtime. The biological architecture proves remarkably resistant to environmental variation, functioning effectively from scorching savannahs to dense forests.
The elephant's durability derives from self-repairing biology. Minor injuries heal, and the system adapts continuously to changing conditions. However, population numbers have declined from an estimated 10 million in 1900 to approximately 415,000 today, suggesting certain vulnerabilities to anthropogenic pressures.
The Internet
The internet, in its recognisable form, has existed for approximately 35 years. Hardware components typically require replacement every 3-5 years, and the underlying protocols undergo continuous revision. No single physical component of the original ARPANET remains operational. The system persists through constant regeneration rather than individual longevity.
Yet this architectural approach confers certain advantages. The internet evolves more rapidly than biological systems, adapting to new requirements within months rather than millennia. Whether this proves sustainable across geological timescales remains entirely undemonstrated.
