I don't think that's entirely fair to say about touch screens. Being born just 3 weeks before lockdown my son has grown up with screens as a way to keep in touch with family. Children love to touch things, and my boy loves swiping up down on the notification screen of phones, but he doesn't know *how* to use a phone. We also have laptops with touch screens, to do our work, and he'll come over, touch the screen and realise it responds. A TV is just another screen to children, no different to a phone or tablet, only bigger. My boy will try to touch TVs to see if they act like a phone.
I don't see how having a TV on in the background all day is any better than letting a child touch your phone? If it's just part of your daily life is it really that big of a deal? Would it be better if Ron knew how to use the remote for the TV instead?
