"Is it really Ah-Chen?" is a question of value, which is up to Shen Chun-lieh in the first place.

That he, or we, have value algorithms that get confused and contradictory in situations that humans have never faced is hardly surprising .

Values are choices. Identity masquerades as a fact, but it is fundamentally about value, and therefore choice as well.

This is brilliantly succinct, and I am stealing this explanation. Thank you for articulating it.
