Not quite right Dr GC.
1) Cities exist because of geographic location in relation to trade.
2) Cities evolve diversity because they were well run, because they developed rule of law among a homogenous people (excellent) and attracted more trade.
3) The utility of such diversity is limited to single digits of the population.
4) While with every doubling of population, density provides an increase of 20% of everything, that means both everything both good and bad.
5) Cities like empires generate demand for authority the produces rent seeking bureaucracies.
6) The ‘excellent diverse’ cities are genetic sinks (dysgenic).
7) We have never been in the condition where the majority lived in cities and this appears to produce extraordinarily destructive externalities that we are only now beginning to understand.
8) We are no longer in the condition where cities are advantageous for skilled labor, because the opportunity cost and transaction cost of communication has approached zero.
9) While Mr Musk is re-demonstrating the importancde of Ford’s discovery of producing the entire value chain of production, this is not true for most production in an age of easy transport of components between areas of production. Ergo there remain and will remain a vast distsribution of labor and competency and capital for most production. Most famously the current 900+ companies worldwide it takes to produce a comupter chip in the most complex supply chain we are aware of. As such the only utility of density today is reduction of infrastructure costs and providing cheap labor for distribution centers (amazon). Imagine what’s going to happen when all those women we added to clerical work over the past fifty yeares are replaced by automation.
