We all know that diverse teams work better but better efficiency is not the only reason that we need to promote diversity. We need to promote diversity because naturally, we are diverse! We cannot change to be the same so we need to learn how to be diverse and get the most value from it. This is an existential threat if we cannot manage the diversity. The only other solution than managing diversity is being the same. It is trivial that this is not possible and it means conflicts and disasters which we as human-beings have experienced before.
