As we all know, computers are very good at some things, and much less good at others. You can use a computer to find a spelling mistake in a book that would take a person ages to find. But you couldn't ask a computer to reply to a complaint from a customer, or at least not to a customer you want to keep. In training and education, much attention is focused on the idea of using computers to teach. A holy grail for some is to make a computer like the best possible human teacher, but one that can be duplicated infinitely and available to all.
Computers really score when asked to do precisely defined tasks.
They are good at doing things fast. And they are good at doing the same thing over and over again. But they are bad at understanding how people are responding to them and at reacting to unforeseen circumstances. A good teacher or trainer needs the latter qualities more than the former ones. The truth is that computers, at least today, are not very good teachers or trainers.
