Particularly I think that anthropology is always open to new challenges. Because, in view of the nature of its object of study: the society –rather Culture - in all aspects…in the past, present, future; about religion, politics, routines, rituals, etc. the science of anthropology must be adapting the hole time at it. So it field is always increasing. That’s one of the special features of anthropology: the large magnitude of it scope.
So, about technology, anthropology can act like a mediator between the distribution of this, rather the diffusion of technology inside the world. Anthropologist also can teach to individuals of some places, societies, even cultures, things related to uses and technology which they ignore. This applies in the anthropological studies about the paradigm of “human develop”, I mean, when we want to change a poor reality implementing technology and teching to the people to use it; for example in rural areas anthropologist can design a project which includes tractors, fertilizer and other stuff according their reality. These of course has a social background that cannot be ignored. Because we can’t intercede in a reality without knowing about it social dynamics. And that is an important challenge: how to mediate between human groups without conflicts.
