Mario
Mario's documented existence spans 44 years as of the current date, a remarkable tenure for any commercial entertainment property. Nintendo has carefully cultivated this longevity through strategic releases, quality control, and protective intellectual property management. The character has outlasted countless competitors who emerged and faded during his reign.
However, Mario's continued existence depends entirely upon corporate decisions and consumer interest. Should Nintendo cease operations or public attention shift permanently, Mario would exist only as a historical artefact, preserved in the amber of nostalgia but no longer actively propagating.
Procrastination
Procrastination predates not only Mario but likely predates Homo sapiens itself. Behavioural scientists have observed procrastination-adjacent behaviours in primates, suggesting this phenomenon may have roots extending millions of years into evolutionary history. The first creature to delay foraging when foraging seemed tedious was practicing proto-procrastination.
More significantly, procrastination shows no signs of diminishing. Unlike species or products subject to extinction, procrastination appears to be an emergent property of consciousness itself. It will persist as long as sentient beings exist with tasks they would rather avoid.
