I doubt anything will look different, except for more sprawl. If I look at my home town 30 years ago, it's essentially the same. In 30 years we just widened the freeway and added a bunch of new housing developments and some shopping centers.
Thirty years isn't enough time to effect major changes.
Did you guys read the James Altucher piece "NYC is dead forever -- here's why"? It sheds light on the most adverse impacts of the Covid pandemic on NYC. It is difficult to argue against his points as well. With so many restaurants and businesses being permanently closed down, coupled with the mass exodus of people, NYC might just cease to be the throbbing city it was until March 2020. An unimaginably large number of office buildings have remained empty, and companies have no incentive to phase out remote work, especially since it saves them money that would otherwise be spent on essential physical infra spending and maintenance. Employees have reported more productivity, thanks to improved bandwidths. So: really no incentive for companies to eliminate remote work. If anything, they're getting more out of employees for the same pay (or reduced pay--depending on the industry you're in).
In sum, the piece argues that cities that were until now Tier 2 may become Tier 1 -- financially and culturally. Work is definitely going to change further. Remote work is highly likely to become the norm, with the exception of brick and mortar industries. For a while now sociologists have also been suggesting that the nature of work would gradually change as we progress further into the 21st century. Homes will be reimagined; home offices will not be an elite thing only. A significant number of people would work remotely. Yet, this is not all rosy. The inability to separate work from home will also mean employers will regulate more than just our "work hours." We are likely to be subjected to increased monitoring. The pandemic, they argue, has only accelerated this process.
