Dialogue is not a form of worldbuilding

Every other day I see a post in this sub with a "worldbuilding example" from a show or movie that is just a bit of dialogue between two characters where one explains something about the world to the other. This is not worldbuilding. This is a cheap trick used by unoriginal writers to circumvent the problem of exposition. Exposition is a problem inherent to any work of fiction where some information about the world is necessary to understand the ongoing events. However, this does not need to be spelled out to the viewer in so many words. All we need is to infer from context. The world can be built by showing the reader its moving parts rather than telling them "This is how the world works."<br><br>I cannot think of a single instance where this sort of dialogue has been used tastfully. Hard sci-fi is not exempt. I see this form of exposition used in 2001, Bladerunner, and Dune all the time. It was completely uncessary in all of these cases. Nothing is lost by removing these scenes.<br><br>I think that a more tastful approach would be a scene where one character of a foreign culture/subculture asks common sense questions about the protagonist's culture that they had never thought about before. This can be used to build aspects of the world without feeling forced or unnatural.
