All computers would have to have facial recognition in their system and although there is no mention of cost in the article one can imagine that this new technology is not cheap. Is it realistic to expect that schools will pay great amounts of tax payers dollars just so that we can invade the privacy of our children to figure out if they are bored? It seems much more financially sound to not steal the jobs of millions of teachers and let them get to know their students, opposed to scanning their face.
