I think it was talking about the rapid-fire editing techniques and how they affect cognitive development. However, it is a rant of a slightly different kind to mine....excepting it does place the blame squarely on us, that is the middle-aged people who run society, and not you young folk.
It's our marketing, and our obsession with style over substance that leads to this: it is our institutions, our values, our need for excitement which is driving down the attention spans of you young folk, and those of the generation below you. The accountants demand that we maximise profits at the expense of thinking.
All praise the almighty dollar.
