I can't help but point out that smartphones (with the apps typically found on them) are essentially on-demand dopamine devices. Pretty much any game or social media app you can install has as its primary goal to get you addicted. That's their business model.

Very little can hope to compete for a child's attention against such a device. In fact, I think even the fact that we are allowing children to be exposed to this when pretty much everyone agrees that they should be protected from drugs (alcohol, nicotine, etc. included) is kind of crazy.
