My immediate response is that this is clearly good news - a gradual reduction in population is a good thing. We just need to work on managing the societal practicalities properly
Reductions in population will happen after the climate change issues go unresolved when they needed to be, and resource scarcity forces an economic global crisis never seen in modern history. It won’t be gradual. Every pop model predicts going from 10B to 1B in less than 100 years post vertex. Or at least it seems if we stay on the track we are on.
