Bingo!
We finally got there.
The issue is not going to be under or over population for much longer - but a complete absence of jobs and purpose as AI develops and most work becomes obsolete.
And dare I say it, a potential huge chasm of those with purpose and viable employment and those that are totally left behind. You think the Industrial Revolution created problems, that is going to be nothing compared to the 4th revolution that is just beginning.
We should be culling birth rates in anticipation, and schools and students should be considering how AI might affect them and future careers.
It is the creep affect, supermarkets now have more and more self service tills, same with fast food outlets, passport gates, car parks, flight desks etc. It’s already happening everywhere.
