Arthur C. Clarke hypothesized that "our technology must still be laughably primitive; we may well be like jungle savages listening for the throbbing of tom-toms, while the ether around them carries more words per second than they could utter in a lifetime".

When Banks is able to establish sufficient shared vocabulary to ask why the aliens have come, they answer with a statement that could be translated as "offer weapon". China interprets this as "use weapon", prompting them to break off communications, and other nations follow. Banks argues that the symbol interpreted as "weapon" can be more abstractly related to the concepts of "means" or "tool"; China's translation likely results from interacting with the aliens using mahjong, a highly competitive game.
