Albright (Univ. of Southern California) argues that "untethered" is the key concept to understand how youth live with technology. Disconnected from traditional modes of social inclusion, including marriage, religion, and permanent employment, they no longer pursue the same life goals as previous generations, suggesting that they are reshaping the American dream. Instead, highly connected via technology, youth are forming new values that include flexible lifestyles, immediate gratification, and social awareness, as Albright argues. Marriage, permanent jobs, religious affiliations, and other traditionally important values no longer matter as much, disrupting old social norms and even changing the world's economy. Albright's work helps readers better understand how youth think and act, and why they do what they do, even beyond the confines of technology. While the book underscores the challenges and opportunities brought about by mobile technologies, it offers insights about overall social norms among the digital natives. The causal relationships she establishes between the use of technology and youth's behaviors may not exist as strongly as she hints, but she is absolutely correct that the untethered world is filled with opportunities for cooperation and collaboration.
