Can computers replace teachers?

This article was very interesting because I have taken online classes and obviously regular classes. I feel that I need the interaction of a teacher to genuinely understand what is going on in the class and I hate having to interact via email. I think online classes are a good idea, but teachers should never be replaced because the interaction needs to be there with student and teacher, and it has to be face to face. It sort of scares me to think that this could happen in the future with technology fully replacing students. But I honestly don't think computers can fully replace a teacher.
