Where I live, our government is pushing this sort of technology in our schools. I have opted out, we personally don't want it for our children. I'm lucky we have that choice at the moment, I think in years to come though, there will be no option. Not if you want your children to attend a conventional school.
You're right, parents have a lot to answer for. The sad truth is though that most parents have no idea what's really going on and most of them themselves are also addicted. How can we expect someone who is already addicted understand the dangers it poses for children?
