Final answer:
Karen calls Mr. Roy a Luddite because he chooses not to own a cell phone, reflecting a modern use of the term that defines a person who deliberately avoids using certain technologies.
Step-by-step explanation:
Karen labels Mr. Roy a Luddite because he doesn't own a cell phone. The term Luddite historically refers to a group of early 19th-century English workers who destroyed machinery, especially in cotton and wool mills, that they believed threatened their jobs. In modern parlance, a Luddite is someone who opposes or is skeptical of new technologies and the changes they bring. Being a Luddite is not about the lack of understanding of technology; rather, it's about the choice to reject certain technologies due to values, skepticism, or preference for what is perceived as more traditional methods. This choice might be seen by some as a stance against the coldness and alienation that technology can symbolize in modern life, contrasting with technophiles who embrace innovative gadgets and advancements.
