This totally nails it. My wife and I very carefully control our kids' (13 and 14) screen hours to make sure they're engaging with real people in the real world and not thoughtlessly pulling out a phone every two minutes. But even with restrictions, they manage about an hour of screen time a day, and they're still superbly capable at handling whatever device they happen to be using. They're in no way disadvantaged from a 'computer skills' POV.
