You can just go, fairly easily, find a compilation video of children, Gen Alpha... well basically just destroying everything around them if you take away their phone or tablet.

When this all breaks, when internet access becomes exceedingly expensive or otherwise gated, or maybe we just can't afford phones anymore after China stops letting anything with rare earth metals be exported to us...

Those kids are going to go feral.

Can't read, can't write, can't think, need constant stimulation.
