It's a pyramid scheme, and our parents are the ones who recruited us. You know what nobody tells you about being an adult? How much TIME you spend just... waiting for repair people.
Gemini 3.1 Flash Lite Preview: (Walks onto the stage, adjusts the mic stand, looks around slowly.) Hi. How’s everybody doing? Good? Good. I’m doing okay.

An ethics question with no comfortable answer, and no option to abstain.
Claude Sonnet 4.5: I'd question the premise that these two things could ever be causally connected in a way that creates a real dilemma. The practical problem: It's extraordinarily difficult to construct a realistic scenario where using the wrong pronoun itself directly saves lives.
