This is the famous question posed by my good friend Sung.
In the modern age, you hear all the time about artificial appendages and artificial organs. For example, if someone was in a tragic accident, they could get a robotic arm and a robotic leg if needed. You also hear about artificial hearts and iron lungs.
So, pretend you slowly replace part by part. Sung’s question is, at what point does the person cease to be called human?
