Some interesting points, but I am a bit discombobulated because the author keeps changing between education, schooling, and parenting pretending they are the same.

Is he asking how to parent a child or what fields to nudge them towards, or what?

I am lost in him taking formal education not delivering any more and making it into an existential crisis of parenting.

Is parenting "education"? sure to some extend like do not stick your hand in fire and some such. But that is a far cry even from basic calculus.

Maybe just stick to the basics on what to teach your son, and of the four things written, only the first and last really needed - become a good person; learn basic facts. The other two will fall in place.
