Isn’t that exactly what parent comment’s promoting? His kids were bored with a relatively unstimulating toy, but they reached their breaking point and learned how to have fun with it.
Children are only bored for so long before their imagination and natural instinct for curiosity and play takes over. Supervising and forcing boredom onto them at all cost as they find ways around it is not something I believe is the intention of the article.
I think the point is addressing the urge to endlessly entertain and busy up children constantly instead of letting them just sit and figure it out on their own.
