He says that 2/3 of the "broad trends in the relationship landscape that suggest heterosexual men are in for a rough road ahead" are exactly what I laid out in the article. He mostly just agrees with me, and that has me question if you actually read the article before sharing it.
He just adds on top that many men aren't able to navigate the inequity they're facing on dating apps because we don't teach men proper communication skills, which is a far cry from your claim that men are eschewing self-improvement and remaining mediocre. It should also be noted that he doesn't cite any statistics to that last point, just to the first two (which were already made by me).
