A very powerful article from a former Chief justice. We would all do well to take heed of his warnings:

Too much screen time means an increase in eye-related problems. If the home becomes a school, then there is no escape for the student from the prison of the home-school-screen There has to be a certain requirement of actual vs virtual school time, failing which the school should be considered closed.

All the stuff that a computer can do should be used to improve the "classroom" experience. Perhaps students will be the best judge of what may be done; and left undone.

Too much screen time will cause eye related problems. If the home becomes a school, there s nowhere to escape to. There has to be some real school-time: It cannot become an entirely online year.
