The way we treat screentime these days feels like a strange continuation of the way it was treated for those of us who were kids in the early 2000s even though the world has changed significantly since then.
I remember that back then schools and TV shows were all pushing this idea that all screen time was harmful for kids and to not let them have more than an hour or two a day.
It may have made some more sense than nowadays since CRTs were more common back then and seemed to strain the eyes more, but the lack of differentiation between actually productive screen time and plain old replaceable entertainment caused a ton of friction in my family as I was growing up.
In comparison, with my currently 5 year old niece and 1 year old nephew (more visible in the niece of course), having access to productive screen time has been pretty impressive for her development, with her having learned the alphabet, developed a decent vocabulary, learned addition enough to even reason about numbers for which she hadn't memorized the answer, and even picking up on some multiplication, all before starting school.
