The characters in "The Hydrogen Sonata" by Iain M. Banks focus primarily on conversation, which seems to be an inherent trait of organic beings. Their dialogue appears to serve a purpose beyond mere communication, as it helps to create an illusion of control over their surroundings, whether it's a ship, fleet, or entire civilization. This reflects a deep-seated need for assurance and connection among individuals.

The emphasis on talking highlights a larger theme of the book, suggesting that the act of discussion is a means of coping with uncertainty in a complex universe. Through interactions, characters navigate their realities, reinforcing their sense of agency while grappling with the implications of their existence and choices within the vastness of space.
