This is touching on linguistic determinism—the idea that the words we use limit or expand how we think. If gemini floods conversation with “nuclear” imagery, it could theoretically lower the psychological barrier for people to think in those extreme terms.
I had quite a few conversations on different topics, completely unrelated to war, where gemini used this expression “nuclear option“ sometimes even multiple times within the same conversation. It preferred this expression instead of “the last resort“ or “worst case scenario“.
If gemini has millions of conversations with people where it drops this expression randomly, the psychological impact will be significant not to mention that people will pick it up and use it more often then before amplifying the effect and slowly creating a tolerance and acceptance with actual nuclear war.
