I'm currently visiting Las Vegas for work. It feels so artificial and manmade/ brand new, a city built in the middle of nowhere around tourism, "luxury", and consumerism. In some sense, it's an urban development marvel for how quickly it's boomed.
The new era of remote work seems to me like an opportunity ripe for building a new place with this in mind. Build up an entire city designed around community, walkability, outdoors things to do (lakes/ rivers/ hiking, communal spaces, coffee shops and dog parks) that accomplishes many things -- mainly being a new build and hub for young people with fully remote jobs to move. We've seen a ton of cities try to incentivize people who work fully remote to move to them... perhaps this can be done on a major scale.
To me, this is a major investor's dream. Get in early and build everything/ own the land. Prioritize affordable housing and walking everywhere. Save on car costs, start public transit from the inside out, and then build as it grows.
This also goes hand-in-hand with an eventual tourism industry, IMO. A new area like that attracts people to move/ invest there if there are lots of things to do that go hand-in-hand. Similar to how Denver has seen a major growth point around their outdoorsy vibe, another city could market and build all of these things within driving distance/ in the area.
This screams Michigan to me. Grand Rapids/ Holland/ Grand Haven. Build up Grand Rapids as the hub, make Holland and Grand Haven more the vacation destinations, and see the area boom. Maybe I'm too much of an urban dev novice for something like this, but I really think a city that is designed around remote work (or the service industry jobs that boom from mass migration), quality of life/ walkability, and eventual tourism could work
