In Alex Garland's screenplay for Ex Machina, a key quote highlights the imbalance in relationships, pointing out that gaining knowledge about one person without reciprocation undermines the very essence of friendship. The phrase suggests that true connections require mutual understanding and sharing, rather than one-sided exchanges. Without this balance, meaningful relationships struggle to develop and thrive.

This perspective emphasizes the importance of vulnerability and openness in forming authentic bonds. When one party learns extensively about the other while remaining unexamined themselves, it fosters a sense of isolation rather than companionship. True friendships flourish on the foundation of mutual sharing, where both individuals invest in understanding each other deeply.
