Global population is still growing, I think I read it's predicted to keep increasing into late mid century to around 11 billion before it plateaus and starts slowly falling.

The numbers get very optimistic from there will predictions of rebounds and other nonsense that is unlikely but the people claiming it will be long dead.

People who were raised as a single child are far more likely to only have one child so my bet is the population dwindles more quickly than these models indicate.

I agree that the answer to humanity's most pressing issues is lowering our population, but don't think it's a non-issue.

The old keep aging out of the workforce, there's not enough young to keep a viable tax base, utter collapse. Here's where someone says tax the snot out of the rich. I'm down with that! But in a shrinking population, they won't be rich long. Directly or indirectly, all of their money comes from us.
