It's certainly something that has people worried. I suspect a population decline and unbalanced demographics with too many old people per working age person are pretty much guaranteed. But personally I don't think it will be catastrophic civilisation level collapse. But at some point things will rebalance and turn the other way as resources, housing and such become more abundant.

I'm also hopeful we sort out the problems with big tech eventually. I was initially against it, but I'm starting to think Australia's plan to ban under 16s from social media is actually a very good idea.
