I’ve noticed something. If you ask someone “would you like to commit suicide?” the answer will typically be “no”. There are specific unusual circumstances (terminal illness, depression, advanced age, etc.) in which people are sometimes inclined toward suicide, but for most of us, most of the time, it is an obviously undesirable proposition. But if you ask the same people “would you like to live indefinitely in your twenties with the aid of nanobots” the answer will also typically be “no”. These answers are contradictory.
