What suggests a stable population to you?<p>Developed countries are all dropping below replacement fertility rate, sustained only by immigration and the higher fertility rate associated with recent immigrants.<p>I haven&#x27;t seen any evidence for a stable point of population - it looks like it will grow, until it begins to decline in the not-too-distant future.  Then does it ever stop declining?<p>Does it stop declining at a point we can sustain a technological society, much less technological progress?<p>That&#x27;s my vote for resolution of the Fermi paradox.
