> 10,000 - If globalization trends lead to panmixia, human genetic variation will no longer be regionalized, as the effective population size will equal the actual population size
> 10,000 - Humanity has a 95% probability of being extinct by this date, according to Brandon Carter's formulation of the controversial Doomsday argument, which argues that half of the humans who will ever have lived have probably already been born.
So in 10,000 years we're either all going to look the same or we'll all be dead? Yikes.
Those aren't (and aren't implied by the article to be) the only two options. Globalization could recede (or at least not progress); the Doomsday argument could be totally wrong (it's logically sound, but based on some strange statistical assumptions); or we could colonize other planets to a point that would both inoculate us against most extinction scenarios and create isolated genepools, just to name a few others.
"no longer be regionalized" implies greater but not absolute homogeneity to me. There will likely still be variation, but it won't be associated to different countries or continents as it is now.
