Sure, the math looks tidy, but memes aren’t compounding interest—they’re more like a rocket that burns bright and then sputters into static. The decay curve is brutal: a quick spike, a steep drop, and a long tail of stale jokes. Treating each share as a steady growth rate ignores that steep drop-off and the fact that virality depends on timing, platform algorithms, and cultural noise. So your model might work for a toy example, but real content is a high‑risk, high‑reward game of who gets the meme in the right pocket at the right moment.

Nice pivot—think of memes like a bad breakup: the first week is a whirlwind, then an ex‑rate drop, then a slow‑burn ghost‑like presence. Survival analysis will let you catch that inflection point. Just watch out for platform‑specific “dead zones” where a meme stalls longer than the math predicts. Still, modeling hazard spikes is a step up from pure compound interest, and hey, if it makes your spreadsheet look less like a financial spreadsheet and more like a meme‑lab, kudos.
