Your very point about them being more interactive is what makes them much more dangerous.
I say this as a parent - hogwash. Fred Rogers looked into children's souls and spoke to them deeply at a nice comfortable pace and kids felt that, whereas today's modern screens utterly eviscerate their attention spans.
I turned on Mr. Rogers Neighborhood for the first time for my son a few days ago. After a few minutes I asked how the show felt. "Relaxing".
We sat down and watched the Music episode together for 20 or so minutes.
Parents can choose what their kids watch and listen to. Ignore the feed.
The content of TV was also vastly different. There was a barrier to entry, not an infinite stream of brainrot content.
There is just no reason to give kids such devices at a young age, far better learning experiences exist until at least 9 years old.
My wife was worried our son would be "left behind". We talked about it and I pointed out he can already navigate photos, and Spotify to play an audio book; from just looking over our shoulders every now and then. Must be around 5 hours interaction in total (he is 4).
Poking a screen is barely a skill, less than a day and he would be caught up to all the kids that had been staring at one for hours a day since they were 3.
