This is what the comment quite literally claimed: "instead of learning (without getting bored at all!) about the reality that they are one day going to have to navigate by themselves". Later added in comment " missed opportunity for the developing brain to learn about the world, its sights, its sounds, its interactions, its physics, its rules. Everything."

It is opposite of what you say. It claims it wont be boring, but that it will teach them to navigate themselves which they wont learn otherwise.
