Good that this is posted as a joke because Dr. Curry is apparently a political science teacher educated at a school of economics, and not an evolutionary biologist or even a biologist as far as I can tell.
No doubt he sees himself in the line developing toward the "attractive intelligent ruling elite", but if he is an
actual evolutionary biologist he might consider himself to be a link toward the other less intelligent group.
This theory has so many holes in it it's not worth shooting at.
I'll leave that to people with more time on their hands.Suffice it to say his true intent might be better divined by what he thinks will happen to homosexuals in this future split up between unsuccessful men and women (small penises and boobs, respectively I assume) and successful ones (all of those who figure out how to make easy money with shams and schemes - for instance using say, pseudo-science

).
I suspect his thinking would be equally shallow. Edit to add:
Actual information on what speciation is and how it occurs, and a
brief description and history of eugenics which is what doctor Curry's theories are bordering on, since the most likely human speciation would be human-generated.
