It is essential to HoloWorld that there is a rich diversity of different cultures. HoloWorld is not one uniform culture. It is not just a global inter-connected society where you find about the same no matter where you go. HoloWorld is global, yes, and it is very inter-connected, yes. But it is also very diverse.
Diversity is in part arrived at by allowing it.
There will be no central authority that tells people how they must live. A worldwide communications network might very well cultivate increased understanding and appreciation of our differences. It might also allow many new cultures to develop, no longer limited by geographical boundaries. People of like preferences are able to find each other, and to cultivate their mode of living together, where otherwise they might be forced to subordinate themselves to only what was available in the location they live. Unified but bland cultures have often been imposed, not merely by contact, but by overwhelming force.
