text: In conclusion, the Facial Action Coding System will benefit classrooms all across the globe. It'll be able to detect the students' emotions and report the information back to the teacher. Then the teacher will then know how their students feel about the curriculum and if they need extra help or not.In my opinion, we dont need cars that drive on there own. A big reason is because people today are already not very smart, and a car that helps them drive will not make things better. they wont learn to do things on there own, and wont beable to teach younger people, they'll just have a car that drives for them.
