[2212 안진서] I agree with you that there are many difficulties in replacing robots with teachers. But I think it's okay to have robot teachers in some subjects. First of all, at the school level, bringing a robot teacher is much cheaper than a human teacher, and it is more efficient because you can teach classes accurately and with a blueprint. And I don't think physical education teachers who have to move their bodies or art teachers who have to have creativity can be replaced by robot teachers. Instead, I think problem-solving subjects such as math, English, and science will not be a problem even if a robot teacher is involved. I think it will be helpful if robot teachers teach these subjects because students can focus only on the class. I'm looking forward to hearing your opinion about this.
