Prabhupāda: He cannot save himself. He can make a machine which will not die, but he will die. Is that all right?
Devotee: Yes.
Prabhupāda: How much perfect he is, that you can consider, that he's making something perfect which will not die, but he will die. So he's imperfect. So how his machine is perfect? This is common argument. He's imperfect. But he cannot make such machine that he will not die.
Satsvarūpa: They say in the future they will...
Prabhupāda: Oh, that is, that is a... Kicking, they on their face. That is the only loophole on which we can kick on their face. You see? They are making machine perfect, but they cannot make themselves perfect. Why don't you ask that "Why don't you make a machine that you'll not die? Your machine will not die, I accept. You're so perfect. But why you will die? Why you will die?" What is their answer?
Siddha-svarūpānanda: They say that they will get to a point where, when each cause of their death, maybe, say, a bad heart, then they can get an artificial heart.
