Postman is well, well worth a read. His observations on TV, before the internet was ever really more than a curiosity, can be just as easily applied to what the internet tried to do.
The problem is that we're not, collectively, any good at actually asking any questions before deciding some new bit of technological wizardry is worth using. We don't consider the opportunity cost (that's a lost concept these days), and the running question seems to be nothing beyond "Can I imagine some possible way in which I might find this useful?" If it turns out not to be, well, we're already in the system, and sunk cost fallacy applies hard.
I read Technopoly not too long ago, and by the end I found myself grieving that Postman still wasn't alive to write about the world we live in today. He predicted it in the early 90s, I can only imagine what he would have to say now, 30 years later. I can't imagine it'd be good.

But, yes. Read Postman. He's very insightful.
