David is the name that in Hebrew means "beloved".
In "Artificial Intelligence" (Ai), David (the first robot designed to love humans) is a perfect reproduction of nature, an imitation of reality, a recreation of a needy child.
A mechanical materialization of child innocence and wonder, David is a more perfect recreation of God's image than the "Orgas" (Organic beings).
David is also a showpiece sculpture of Renaissance, representing the Biblical hero David, and it came to symbolize the guard of civil liberties in Florence. That statue is an interpretation of an usual ancient Greek motif of the heroic male, a symbol of strength and youthful beauty.
