Let me play devil's advocate for a minute. Why is this "new" addiction wrong ? What does it mean to say it is bad ? pg is taking great pains to distance himself from real addiction, like crystal meth. Yet he never explicitly explains anywhere why the new "addiction" is actually bad , other than trying to loosely associate it with alcohol. I don't think that the "addictiveness" of a thing alone is enough to call it ba…
I would take the moral relativist approach to arguing that these things are bad. Suppose a hypothetical person who spends time on (e.g.) Facebook when there's something else they themselves would prefer to do with that time. Would the addiction be bad for this person?
If so, we only need to point to the existence of a statistically significant number of such people to substantiate the argument that their Facebook addiction is a "bad" thing. Unless we have reason to believe that Facebook addiction in general (not Facebook itself, just addiction to it) has benefits, we can transfer this to Facebook addiction in general.
Here's one person so identified: http://www.cnn.com/2009/HEALTH/04/23/ep.facebook.addict/inde...
To my knowledge, nobody's done a study of this, but I find it more plausible than not that there exist many people who spend time on Facebook that they would prefer to use doing other things.
I've picked on Facebook quite a bit here. This is not in any way meant to be a dig against the service or company; Facebook is just a convenient example.
