Digital divide is also a barrier, in which internet inaccessibility poses a problem in convergence.
Network convergence works on the basis of information flow for the purpose of decreasing the variance among the views and beliefs of the participants involved. Among a nation, these participants are the nation-states or ethnic groups. “…variance between groups or national cultures would become smaller over time as a result of international communication” (Barnett & Kincaid, as cited in author_last_name, p.159). When information flow is efficient and repetitive, network convergence will be able to unite the participants, and as a result, all the participants will achieve the same national identity due to decreased or even diminished variance among them.
Yes, I believe so because universal culture will promote a universal set of accepted beliefs, values and standards. This will lead to lower variance and difference of opinions and perspectives among people of all nations.
