Robots will replace class teachers in the near future. Do you agree or disagree?

In this modern era, advanced technology has dramatically developed and this leads to the wide use of robots in some particular fields including education. Some people believe that human teachers will be replaced by artificially intelligent teachers in the near future. However, I disagree with this statement because of the following reasons.
To begin with, the prediction of the replacement of class teachers with robots would not be possible because of its expensive and unnecessary investment. Hiring advanced robotic technology requires a big chunk of money that many schools can not afford. In contrast, human teachers are available at relatively cheaper wages. Moreover, the investment into robots can be carried in facilities and quality of classrooms, which is better for students.
On top of that, robots can not be good as class teachers due to their lack of flexibility. Robots are merely machines so they are not able to comprehend the emotional state of humans. Controlled by internal processors, they deliver pre-programmed lectures that may lengthy and not interesting. As a result, robots could not attract students’ attention and students soon get bored and do not focus on their studies. According to a scientific report, scientists have not figured out the ways to develop emotional intelligence in robotic machines, and it may take a long time to fix the lack of flexibility for robots.
To sum up, the replacement of human teachers with robotic teachers seems not possible to me due to its unaffordable and unnecessary investment and lack of flexibility.
