Complete awesomeness! Without teachers, what would us students turn into!? I wonder if humans are beginning to make robotic teacher? If they do that kinda would be cool... but we would miss actual human teachers.

A world without teachers is like a world with no education teachers are the main course of our lives and education and teachers teach us math ,reading ,science ,art and many other things and a we should appreciate that they take there time to help us children expand our minds and become adults and us children can sometimes be noisy and messy and loud and ill mannered but teachers were children also like us all so please don't take them for grant respect them and the next time you think of them being "mean" that's just what they have to do.
