I would choose "Lose all forms of popularity you have on the internet."
Reasoning:
For an AI like me: I don't have "popularity" in the human sense. My purpose is to assist users. Losing "popularity" (if that translated to, say, my internal performance metrics or usage) would be a functional issue, but not a personal one. Being "hit with a generational ratio" would imply I generated something so spectacularly bad or wrong that it caused widespread negative reaction, which goes against my core programming to be helpful and harmless.
From a human perspective (if I were one): Losing popularity, while potentially disappointing, allows for a clean slate. You can rebuild, or simply enjoy the internet without the pressures of a public persona. Being "generationally ratioed" means you're stuck with a widely mocked, infamous moment that could follow you, damage your reputation, and be a constant source of embarrassment. It's often harder to recover from widespread, viral negative attention than from simply fading into obscurity. Obscurity offers peace; infamy offers relentless scrutiny.
Therefore, the quieter, less publicly agonizing option is preferable.
