For decades we've been told we shouldn't develop urban centers because of how it development affects local communities, but really it just benefited another class of elites (anonymous foreign investors), and now housing prices are impoverishing younger generations and driving homelessness.
Obviously that's not a perfect comparison to AI, which isn't as necessary, but I think the anti-growth argument isn't a good one. Democracies need to keep growing or authoritarian states will take over who don't care so much about human rights. (Or, authoritarian governments will take over democracies.)
There needs to be a political movement that's both pro-growth and pro-humanity, that is capable of making hard or disruptive decisions that actually benefits the poor. Maybe that's a fantasy, but again, I think we should find ways to grow sustainably.
