Maybe some MAY end up in compiliations in ten years, much like Vines do today. But there will be a million times more tiktoks and a billion times more AI generated videos than there were vines, so if 0.01% of vines became memetic, the amount of AI generated ones will be infintesimal.
Content is all ephemeral on some time scale, but you can cache the near-term content to maximize the views and cut back on compute costs. Some model or human made it (the cost), it's trending (the value), so keep it around for a bit.
Everything has a relevancy and penetration decay curve.
The funny thing is, I think this law applied in the classical era (1950's, 1990's, etc.), we just weren't creating at scale to realize it.
Maybe it's just one dominant variable: novelty. I'd be curious to see how we might model this.
