Yeah, you can argue with advanced learning stuff, and in few cases it would work. But good luck competing with Tiktok, FB ecosystem & other social and attention parasites that probably half of the class will be already addicted to. You are competing with products designed and continuously adapted with massive help of professional psychologists to be as damaging as possible.

I don't think there is 1 rule that would be simply the best solution for every single kid out there. Understand your kids, how they approach learning, stimuli, how they react, how much patience they have (and encourage the good bits obviously). And adapt approach correspondingly, continuously.

But yeah giving small kids phones is a recipe for disaster, even static glowing screen is often more interesting to them than colorful books. Also, lead by example, kids want to mimmick their parents for quite long (usually puberty is stopping this). Same situation here btw (kids, 2 and 3 years old) and we talk about it a lot. We see around us some failures of unrestricted access to computers and phones, but without time machine its hard to say how things would be different without them
