Answer:
I strongly disagree having humanoid robots as teachers. One of the reasons is that, they lack emotions so having a humanoid robot to teach students especially like values, they aren't suited and if a student is in depression they couldn't comfort since they lack emotions. Another is that we have people that are willing to teach others like teachers or educators, so having robots to replace them will let them lose their jobs and earning to support their family.
Hope this helps :)
