What you say makes sense. Humans were once the only means of labor; even animals needed a human attendant – and the cost of construction was the number of capable adults to help build economies. Industrialization, and especially the use of oil and electricity to do work, decoupled man-power. Computers and the internet have decoupled man-hours, and now we see economies of scale, and an information economy. With AI, we may see even less dependence on human labor. What will this do to the human population? With low skill labor made irrelevant, how will those people contribute and receive money from an increasingly gated economy? Interestingly, food also benefits from economies of scale and automation. Cheaper food leads to a larger population. Larger population means more people contributing to the economy, but as we've already seen in farming this last hundred years, fewer and fewer people of whom the economy pays wages to. It's a strange balance. I do not know what it all means.
