Robots are cool and all, but considering our (in a larger sense) children is literally the future of our civilization. The next generation is why it’s important to fix our mistakes, to leave things better than we found them, to open new opportunities and greater potential. Automation can enable that but is not a goal in itself, or is a short term goal for personal gain.
So yes, I’ll agree that we seem to have passed the healthy carrying capacity of the planet and should fix that. However I’ll strongly disagree that it would be a good thing to drop below the sustainability of current society, innovation, science, and I’ll strongly disagree it’s desirable to drop population fast enough to destabilize societies, economies, or to cause human suffering. That’s what we my be headed for. A few tweaks now, might help population level off and gradually decline without causing suffering, and hopefully level off at a healthy total.
Let’s fix our mistakes while still setting the next generation up for success, not give in to misery and root for disaster
Edit: if you read the Wikipedia article on degrowth, there’s surprisingly little focus on reducing population and it really isn’t a goal, although an important tool. Pretty much all of the precepts contradict sudden population declines or the aftereffects of that
