I see this kind of thinking here way too often, and thus i decided to start an open discussion, as i disagree and have solid arguments to back me up.
So we have a solid article, and it's almost solely about mollusca. I'll not focus on these "Cthulhu" thingies, but i'm very interested in this part:
We're basically left alone with sexual selection which determines the future of human species. Women chase most dimorphic men. And as height being the most obvious example of human sexual dimorphism, i would gladly take it as an example as well.
But then we have these:
Oh, no, turns out height was never meant to be an advantage or adaptation for survival today and females still craving taller men is just a textbook example of Fisherian runaway. Where is our valiant gatekeepers and their glorious selection now? Turned to dust. Insatiable lust for more dimorphism in partners marked an end for good gatekeeping.
Conclusion/TLDR: Even if females are supposed to be "gatekeepers" for sex and selectors of genetic quality of the species, they obviously fail badly at their job. There could be a factor of natural selection (but that never stopped some species from still going extinct under pressure of sexual selection) but it's no longer the case for humans. Uncontrolled female hypergamy enabled by degeneracy doesn't even select best genetic quality, it just leads human species nowhere.

Put it simple - more sexual dimorphism. It is supposed to signify good competitiveness of future male offsprings and goes perfectly within hypothesis itself: females care about their sons, not daughters. Male offsprings with "good" genes selected by females are supposed to increase likelihood of adaptation and survival. Well, some of us believe it to be. Let's check if it's true.Female mating preferences are widely recognized as being responsible for the rapid and divergent evolution of
male secondary sex characteristics.
New driver of extinction: Adaptations for sexual selection
By analyzing thousands of fossilized ancient crustaceans, a team of scientists found that devoting a lot of energy to the competition for mates may compromise species' resilience to change and increase their risk of extinction.

And what changed so much in human environment for the past several millennia? Technology and progress reduced natural selection significance to basically nothing, it doesn't bother humans anymore. Sexual selection, however, does.Hunt says some scientists have proposed that the energy animals devote to developing these traits may limit
the resources they have available for survival, particularly when something in their environment changes.
That would put species with strong sexual dimorphism at greater risk of extinction.

Fisherian runaway
Fisherian runaway is a model of how sexual selection can lead to exaggerated physical or behavioral traits (ornament) and exaggerated preferences for these traits...
