lol, he's bringing out the blah blah blah in kaworu. long comments are long.
Have you? Do you not age like Lilim, then? [If they don't age, that might also make them immortal - another similarity with Angels.]
The MAGI was quite an unusual case, from what Keel told me. It was created by a female scientist, who actually built three computers to work in tandem, each one a part of her personality - one thought as a scientist, one as a mother, and one as a woman. According to him, it gave the computer the ability to develop conflicting views with itself... 'the human dilemma', he called it. I didn't see the point of creating a computer to be that much like a Lilim, but apparently it was considered quite revolutionary.
