What specific characteristic makes an invention create a high social cost for the user?
Answer
The requirement for another person to assist in operating the device for a simple task.
A gadget that necessitates a companion to help perform a basic task, such as feeding the user soup, imposes a significant social burden. These inventions are considered particularly bizarre because they create a dependency on others for an activity that could easily be performed solo with standard, simple utensils, rendering the machine effectively useless and socially isolating.
