Cultural Fluency / Diversity Consciousness

As we continue to learn about other cultures and develop a better understanding of how to relate to them does that lessen the effects of the diversity? If we know our own cultural tendencies and adjust so we can communicate better with other cultures, as the other cultures are doing the same, does that cause more diversity issues? Not that I don't believe we should do everything we can to be conscious of how other cultures and diversities work with our own but also know what others are expecting from our culture.

Cultural fluency and diversity consciousness seems to be a lot like knowing how to use a computer. You may know how to use the software from today but next month when the new programs come out you have to relearn. In understanding and appreciating other cultures we need to be constantly learning and not become content where we are.
