Hello, everyone. I have no mass–energy equation, but I do have a speeding trolley. This seemingly playful thought experiment teaches us to reflect on our reasons for acting and the responsibilities we bear.

In a highly transparent future, information can tell us who will be harmed. But to justify our choice of route, we must see the faces of those affected—the faces of others. Judgment concerns more than a single act and its consequences; it also expresses the integrity of our character, a sign of our moral soundness. Honesty, temperance, courage, and kindness are not emotional slogans. They are virtues that keep us from losing our way in difficult decisions.

Involving artificial intelligence is not inherently wrong. The question is whether it helps us act well and become better people, rather than merely minimizing harm or performing elegant calculations. May future intelligence illuminate the human heart, stripping away inflammatory rhetoric and labels while preserving judgment and compassion. May you become incisive and upright. Let reasons be open to scrutiny, and let people be treated with kindness.
