In the twenty-first century three practical developments might make this belief obsolete: 1. Humans will lose their economic and military usefulness, hence the economic and political system will stop attaching much value to them. 2. The system will continue to find value in humans collectively, but not in unique individuals. 3. The system will still find value in some unique individuals, but these will constitute a new elite of upgraded superhumans rather than the mass of the population.
