If there is a dominant topic within anthropology it is, and probably should be, the study of relationships. Anthropologists recognize that there are no unmediated, pure relationships. All the ways in which relationships exist, including communication, are cultural activities.
(Miller and Sinanan, 2014, pp. 3-4)
Points:
All human communications are mediated.
They agree with much of the existing literature that technologies changes humanity, but this does not make us better or worse. Humanity is always a project in progress. They propose a theory of attainment, which implies something previously unachievable but will become latent in the condition of being human and soon normalized (Miller and Sinanan, 2014: 12).
Their study does not follow the trajectory of post-human (Fukuyama, 2003) or cyborg (Haraway, 1991) studies.
