I'm a teacher. I don't teach everything through a screen. I use the smart board for some lessons but even then, limited time. I spend most of my day, standing at the front of the class, teaching, reading stories, observing children, working with groups, working with individuals, hearing reading. I think the OP meant jobs that are 'plonked in front of a laptop all day' type jobs. I wouldn't say that describes teaching in the slightest.
