Yep.

We are no longer learning the small lessons of life when we are young, to handle the big challenges of life as an adult. Instead, out childhood is getting extended well into adulthood to the point that we probably shouldn't start going through puberty until in our thirties now. Humanity is becoming more childish.

The problem solving skills learned in maths bad childhood in general, are no longer being learned, as we use tools to do the work for us. Those tools were created by people who could do the working, who did have the foundation. Now we aren't learning the foundations, because we are using competitive cognitive artefacts before we can build the personal skill.

And there is a compounding effect for not learning young, in the same way as not investing into retirement. The later we start, the further behind we fall.
