text: When it all comes down to is it valuable, i would have to agree. If there is a chance that a computer can know how we feel and our emotion, we would eleminate a lot of fear from out lives. Say a kid was getting bullied, and he/she is going through this everyday and hides it behind a smile, we would be able to know that she is going through things and he/she could use some support. Also we could determine the intellegence of classrooms and how well each student understands the lessons taught in the classroom.
