You've really hit on the elephant nobody talks about because talking about actual inborn differences in human ability is taboo across the board. What we will see in the 21st century is a large fraction of the human population fall off the edge where the marginal value of their labor becomes <=0 no matter what they do. They can't change this because they got a bad hand in the genetic lottery, which is not their fault. This is very different from industrialization 1.0. That created a lot of jobs because the machines were dumb, and because economic growth was huge. Now the machines are smart and growth is slow. Welfare state, violent revolution, or absolute surveillance state totalitarianism and starving ghettos. Pick one dystopia. I think welfare state is definitely the least of these evils. Eventually we could fix this with augmentation and universally available genetic engineering, but the tech is not ready and the social, philosophical, and religious understanding and assimilation is even less ready than the tech. The process of cultural adoption cannot even begin until the tech is mature enough. Unskilled labor disrupting AI will arrive long before the means of improving ourselves. Edit: some have brought up the Flynn effect and evidence IQ is growing. Unfortunately even if true I think it's far too slow. Automation tech is advancing much faster with a decades shorter iteration cycle. Doubt digit median IQ growth over decades would probably be required to prevent mass unemployment at the scale of billions and that's pure sci-fi.
