Beeban Kidron has made an engaging if flawed documentary about our enslavement to the internet, and she touches on the abandonment of privacy, the normalisation of porn and the sinister strains of abuse and online bullying. It's a watchable film, though it tends a little too far to the moral-panic way of thinking, with teens cast in the role of addicts, and their elders and betters – those wise, grey-haired academics – telling us the net is bad for them. Surely similar complaints were made about TV, video, and Bill Haley's Rock Around the Clock? Kidron has pertinent points to make about the internet's colossal storage depots and server units, all burning up power: a brutal, industrial reality far from the quaintly conceived "cloud" where we imagine our data floats. Online porn is voraciously consumed because it's free, and abuse is commonplace because it's anonymous, and Kidron touches on the fact that advertising makes it all viable. Advertisers are privy to our web-viewing habits. So are government snoopers. Kidron shows how disturbing it is, while on the other hand showing (to some extent) how liberating the net is for young people. On average, apparently, we look at our smartphones between 150 and 200 times a day. Is that all?
