Tesla
Tesla was incorporated on 1st July 2003 in San Carlos, California, giving it an operational history of approximately two decades. In automotive terms, this represents a mere infant compared to manufacturers like Mercedes-Benz (founded 1926) or Ford (1903). The company's Model S has demonstrated battery longevity exceeding 200,000 miles, and some vehicles remain functional after a decade of service. However, the long-term durability of electric vehicle components remains unproven across generational timescales.
Time
Time has been operational for approximately 13.8 billion years, commencing at the precise moment of the Big Bang. It shows no signs of depreciation, wear, or planned obsolescence. Physicists theorise Time may continue indefinitely, though certain cosmological models suggest eventual heat death could render the concept somewhat moot. Nevertheless, Time's track record of continuous operation across all observable phenomena remains entirely unmatched by any corporate entity.
