I-Am/Consciousness is just another way of saying Atmanic/Brahmanic Consciousness. The I-Am part is Atmanic Consciousness, and the Consciousness part is Brahmanic Consciousness. Before the foreslash is self you as you know yourself, and after the foreslash is the truth of you, no-self, which is timeless and undifferentiated and all that. So the good news is, yes, you are immortal in consciousness, but no, the you you think of as you, is not.
