Productivity went through the roof in the last 100 years. We need less workers to achive the same results, but still it seems to be a catastrophy when the workforce is shrinking. Imagine a planet earth with only 1 Billion people but with the same productivity as now with almost 10 Billion. No poverty, no famine, much less pollution. just my 2 cents.

Maybe that is one of the Great Filters of the Fermi paradox.
