She [the girl above, Kiki Ostrenga] is an extreme case of an enormous uncontrolled experiment that is playing out across the world. Young people’s brains are developing while they are immersed in fast, multitasking technology. No one quite knows what effect this is having.

The culture of childhood is being compressed. Those things that young people once knew at 18, they now know at 10 or 12. No one quite knows the effect of that either.
