I used to agree with (1), but lately I'm inclined to think that this time, it really is different. Very different. And the primary reason is that unlike TV and books, this is an interactive device explicitly designed to manipulate our psychology into using it more, on a scale we've never seen before. Books never had thousands of engineers observing realtime metrics to make small tweaks to make you use something just a little bit longer. TV isn't a bi-directional communication platform that has thrown teenagers into an arena where they're communicating with thousands of people at a time when they're still figuring out how to communicate in small groups.
Regarding (2), I think people are being far too critical. The author acknowledges many of their own missteps, and they're also going through a time where, iPhone or not, their daughter is growing apart from them, and I imagine that's very difficult emotionally. I also feel like they really humanized how budging a little bit on rules here and there can spiral out of control, and how that feels. I really appreciated that perspective.
