This all sounds like cope to me, from people who don’t take AI seriously. Either they don’t think it is as impactful as it already is, or they don’t think we will continue to see exponential capabilities improvement for a while.
Let’s take the likely situation where, AI can do Math, code, biology etc better than most humans ever can and increasingly needs minimal oversight or direction.
The only valuable skills then are social soft skills. This is not that foreign of a concept to humanity, many an aristocracy in times of peace have lived exactly like this, sometimes for generations in a row, Game of Thrones characters like Tyrion, Varys, Littlefinger are all this.
We actually live in a rare time in history, where you could learn some technical skills and advance regardless of your social skills (though even here having good social skills is a huge plus). That will go away. This will feel apocalyptic to the introverted nerd, but probably exciting for other types of people.
Some AI futurists of the permanent underclass meme, believe access to capital before AI gets good enough will be the only differentiator. I doubt that, it will be helpful for sure, but even if you have millions, you’re still going to need friends, a wife, a society etc. The money will diffuse out, marriage being the largest wealth diffusion event in a persons life. In this world, Marriage would arguably be the most important path to social mobility, for men and women alike. This is already true in many countries that haven’t fully entered modernity, it was also true for old western aristocracies.
So finally to answer the posts question, “What shall I teach my son”, well teach him to go and find a place in school. Successfully navigating the high school hierarchy, will be the best predictor of him doing well in society.
