Why did Margie hate her mechanical teacher?

Margie hated her mechanical teacher because she found the machine's teaching style rigid and unresponsive to her individual needs. The mechanical teacher was programmed to deliver lessons at a constant pace, which frustrated Margie when she struggled to keep up with the lessons. Additionally, she longed for the more personal and engaging experience of having a real human teacher, which made her feel isolated and disconnected from the learning process.
