I don’t look at it as doom but just as a period of very rapid change. As the Chinese saying goes, living in interesting times is a blessing and a curse.
I don’t know what happens next, which is both interesting and scary especially when I think about my kids. They could end up living in a collapsing failed state (or worse) or in a post-scarcity technosphere or something I am not imagining.
Except that a cloud of uncertainty hangs over it.
But a cloud of uncertainty is not worse than, say, constant starvation and plagues or eternal tribal wars. Would you bring a child into the world of the black plague? The Bronze Age collapse?
There has never been and will never be a utopia, especially one that can project into the future without fear. Having children means both blessing and cursing them with existence in a universe that apparently is not safety tested.
Resources will always be scarce, and honestly I don't know what people would do or how they would be motivated in a world where they can always have anything they want or need.
True post-scarcity would mean anyone could have their own private plane, spaceship, etc. That couldn’t happen without some kind of speculative singularity scenario where we get Mr. Fusion and benevolent superintelligent AI or something. Star Trek levels of post-scarcity are sci-fi.
I'm sure many Europeans thought WW2 was the end of everything; but the next generation had an incredible boom. It's always darkest before dawn. There are decades where nothing happens, and weeks where decades happen. And all that.
