Atlanta seems to still be finding its identity. All the industries are nascent, it always seems just on the cusp of a big transformation. I have a theory about cities, that property values are largely constrained by geography as the first and practically only factor, and Atlanta has no geographical limitations that jack up prices. As a result, property has always been comparatively cheap.
Atlanta seems to be a big sponge, not even close to hitting scaling limits. I feel like you could almost pour the same amount of wealth that NYC has into the area and it still won't look like even Chicago. It'll just sprawl outwards into adjacent metro areas like Alpharetta or Decatur. Even the city centers here, Downtown, Midtown, and increasingly Buckhead, feel like three distinct cities rather than part of a whole.
As a result it simply won't ever come to have a more coherent identity and message than it did in the nineties with rap and the music industry.
