Can computers replace teachers?

To make it short, a computer is just a machine. It needs programs to come alive, starting with an opearating system. A computer will be as good as people have programmed it to be.

The human mind is something very complex, with reason, feelings, conscience and subconscience.

My point is that before a computer can compute all the ways of thinking of the human mind we will need teachers, their psychology and understanding to make us progress.
