Personal notes on that: we know a classic game who tend to be played at a slow peace in society, efficiency vs flexibility. A city designed today for today's needs is far more efficient than a Riviera. However cities are already built and evolve at a hard and slow peace, especially dense ones, especially parts of them full of tall buildings with many owners etc. Even if we design the perfect Smart City today it will be built only after a certain amount of time (years) and we can't upgrade it much like we do for software releases. So cities are the efficiency side of the game. The flexibility side is for Riviera's (witch in some countries might be called cities, or at least being inside some cities) where people is "a bit dense" but not too much, where we have single-family homes with some ground around (let's say 1k-2km² (~10k-20k ft²) land per single one/two stairs home to have room for future changes) mixed with workspace (small buildings for various activities) and few "more dense" areas for specific activities (hospitals, schools, military/gov buildings, airports, harbors, ...) + some local districts (large enterprises, mining, manufacturing etc). For a certain amount of decades we have pushed the efficiency model, now perhaps 'efficiency' have reached a level where fragility and absence of flexibility is too much so we shift toward 'resilience' witch happen to be given by well-crafted flexibility. The point is: will it be exaggerated as we have exaggerated before? Or will it be too little too late? Or the right amount? Some theorist have crafted a "small-medium city" hypothetical future (UN New Urban Agenda), I have many doubt on it but anyway we need both a certain density for economy of scale and sociability and flexibility to evolve in a changing world. My personal choice is a middle ground but still outside urban area to have room to evolve while being near-enough to urban area to avoid being completely "out of civility", I suspect not so much but not so little others have done similar choices. Not much "talented" but just those who can and care about their future. Future air mobility might arrive in less than a decade bridging the gap between actual-city density and actual riviera density or to have the best of both world in a spread model. That's a dream, a sci-fi one, so something with some valid and solid bases behind, just in need to be drawn more and implemented :-)
