While taken individually, many of the technologies presented in the story seem to be useful or even fun, the world they create is inescapably bland. And it's the inescapability of it that makes it so awful. While on the surface these theoretical advances provide value, they also potentially destroy the possibility of serendipitous interaction, of meeting someone incompatible, of having your perspective changed, of connecting with someone intimately.
For me, the "problems" being solved by the tech in this story are much of what makes life worth living. While building technology, I think it's important to consider the effects and side effects of these things, and to focus on technology that improves and enhances our lives, rather than takes them over.
