Like all risks it doesn’t affect all kids equally either.
Some are less vulnerable for various cognitive reasons just like some are less prone to chemical addiction.
Kids with wealthier and/or more engaged parents or parents with more free time are also less vulnerable. Wealthier kids have more activities available and can often afford to have one parent stay home.
Lastly kids in healthier communities or suburbs or safe urban settings where they can roam free are less vulnerable.
They children of the poor, those with ADD or ASD conditions, and those with less third spaces or other activities are most vulnerable to becoming addicted to endless stupefying doom scrolling and addictive games that pre-train them for future gambling addiction.
It’s not just kids either. The elderly and the isolated become addicted to this stuff.
Addiction engineering is the problem, whether it’s via a phone, a web site, or a chemical.
IMO if you intentionally and knowingly engineer something for addiction you are committing a form of assault.
