Technology can be transmitted even without a shared language. Many people in many societies are bilingual. People are not superior or inferior according to their technology. Groups of people do not own technological innovations. Many people in a group will not even understand a technology practiced by people they see everyday.
Individuals innovate and teach one another selectively.
Occasionally a group will adopt certain cultural forms as identity markers, but such as group may well be bilingual or multicultural in other ways. One cannot simply exclude people from a group because they look different. Groups are mixed. The range of genetic variation in almost any group is large. Reporters should be guided away from the assumptions that make stories easy to write.
