If I had to name something for which diversity was indeed a strength, I’d probably say the Olympics. Perhaps that’s why it’s so hyped.
It’s impossible not to notice certain politically incorrect things while you watch the olympics. With a few exceptions, for example, good swimmers come from a few countries or have surnames indicating that their ancestors once came from those countries. The same thing is true for runners (though the countries are very different). Given how many swimming and running medals are given out, I suspect that medal counts won’t shift as much as people suggest.
For similar reasons, I’ll be surprised if Africa starts winning lots more medals. Many African countries do well in running events, but as their continent gets less diverse, they may even win fewer medals.
South Africa has many more medals, but a brief perusal of the surnames of it’s medal winners coupled with some knowledge of current events in South Africa, would seem to suggest that South Africa is about to embark on a path of winning fewer (not more) medals.
Finally, I’ll close with a prediction that the Chinese will increase their domination of the weird individual sports that no one cares about.
