Yes, I agree with Margie that schools today are more enjoyable than the school in the story. In the story, schools are situated in students' homes, leaving no room for interaction among students. The prospect of studying from a screen and taking tests seems dull.
The routine of inserting homework and test papers into a slot on a mechanical teacher every day becomes monotonous. Writing answers in punch codes is also quite tedious.
Learning together in a classroom offers students a broader perspective on people. Students become acquainted with others and develop social skills. Being taught by human teachers is much more dynamic than being taught by a machine.
If a student encounters any difficulty with a lesson or concept, they can immediately seek help from the human teacher. In contrast, mechanical teachers are pre-programmed with specific lessons and concepts for each day.
When students work on homework, they can collaborate with classmates, making schools today more enjoyable than the school in the story.
