That which is shallow but useful can have its legitimate place in life, though it lacks character: a daily commute on the freeway might suck, and might not match the joy and invigoration of a brisk walk on a beautiful day, but it has its place if you need to get to work miles away and if your area lacks public transportation to get you there efficiently; living in the suburbs might suck compared to the excitement of an upscale urban environment but millions of people manage just fine with the tradeoffs that suburban living entails and get by just fine without the excitement; so too social networking sucks when compared to any one of countless ways of interacting that are intimate, personal, intellectually stimulating, or whatever, and for which the strictures of the social network have no room, but all sorts of people nonetheless get by very well interacting at the social networking level for the utilitarian goals for which they use such services, not caring one whit about intimacy or other elements that make the experience a fundamentally shallow one.

Social may be shallow but it has its place and, as long as we have freedom, you can use it or not according to taste. One can find fault with it but that does not mean it has a "horrible future." Criticism of this sort is thus misplaced, in my view, in spite of the limitations of the venue.
