Population pyramid will correct itself once the upper layers die off
All of this fear mongering that human civilization is about to go extinct is useless.
We only have to endure for two more generations and let the population pyramid correct itself. Once that happens, utopia is coming. There will be less people and too many resources for them.
People won't even have to work. Robots will do farming and food will be extremely cheap or even be distributed for free. And minimum basic income will be given to buy basic necessities.
Most of the labour intensive jobs will go extinct. Only innovative and creative jobs will exist.
Developing new tech, building more automation, providing entertainment, etc. People will passionately do these jobs as there won't be any a need to do anything just for survival.
So let's embrace this short term pain for the next 100 years or so. And then there will be utopia but for a much smaller population than now. No global warming, no pollution, no threat of climate change, no poverty. Just massive abundance and eternal bliss.
