I believe that human differences will be a very helpful when the group works as a whole. While working on a project you will get so many different ideas from all the different backgrounds. Having people from different backgrounds can help make a more diverse device because the group members can give us the distinct characteristics from each background. With so many different ethnic groups the members can learn from each other and their past experiences that could help make the project successful as a whole. I do not think there could be anything that would hold the project back.
