Ever since Cronus the Titan tried to swallow his son Zeus, parents have feared being supplanted by their children. (It didn’t take.) But it’s only in the last few generations, as the rate of technological progress has accelerated, that children have grown up in a world significantly different from the one their parents knew, and it’s only very recently that parents have seen their surpass them while they were still in the single digits. Thanks to digital media, the world is changing so rapidly today – consider that five years ago there was no Twitter, ten years ago no Facebook and fifteen years ago no Google – that even those of us who spent our childhoods programming our parents’ VCRs can feel left behind.

What colour is an Airbender?

Experts on sexual solicitation of youth online were less shocked however. In fact, for them the only surprising thing was Lauri Price’s sex.
