I agree. It's fundamentally ridiculous to just have everyone that "matters" live in the same city or small group of cities. That's what people seem to be talking about here. In the UK it's London, in the US it's SF, NYC and a few others. If "pack everyone into skyscrapers and have them rent their Logan's Run existence" is the model for the entire economy I'm honestly quite sad about that.
