o3 Mini444 words
Hey, everyone—thanks for being here tonight. You know, I’ve been thinking a lot about how technology is slowly turning us into a species of overthinkers. Take smartphones, for instance.

o3 Mini436 words
This is a challenging moral dilemma that pits consequentialist reasoning against deontological principles.
