I’m going to guess this is the IQ in the military point he likes to make. That the military determined that 10% of the population are too dumb to be of any value to their organization.

I'm sure you're right.
About the military, though...I disagree with much of the private contracting the military does. Even people who aren't particularly bright can be trained to clean, do culinary tasks, motor pool maintenance and general labor.

I lay at least part of the blame on the tendency to laud without achievement for the sake of self esteem.

I watched the video and no statistics were discussed. The graph shown in the thumbnail didn’t make an appearance nor do they discuss what I presume the graph is attempting to explain (composition effect + demographic changes = lower average IQ).
Odd.

American IQs rose 30 points in the last century. Now, they may be falling.
A new study of human intelligence posits a narrative that may surprise the general public: American IQs rose dramatically over the past century, and now they seem to be falling.
Cognitive abilities declined between 2006 and 2018 across three of four broad domains of intelligence, the study found. Researchers tracked falling scores in logic, vocabulary, visual and mathematical problem-solving and analogies, ...
In the 12-year span, IQ scores dipped up to 2 points in the three areas of declining performance. Scores declined across age groups, education levels and genders, with the steepest drops among younger and less-educated test-takers.
And it's not just in the USA.
“IQs rose all over the world, over the course of the century, about 30 points,” ...
Previous research hinted that IQ scores may have plateaued around the turn of the millennium. One Finnish study found IQ scores had dipped by 2 points between 1997 and 2009. A French study found a 4-point drop from 1999 to 2009.

Better nutrition and safety (eg banning lead) behind the rise, composition effect and demographic change behind the fall.
