Cities, remote work, offices, etc -- this stuff is cyclical. People will still want to live in cities, particularly young people. Declaring them dead is being too intellectually lazy to look beyond the next 3 years.
Same with work from home. It's probably fine for those who do nothing but email and push paper (like most of the insurance company people in this state), and many of those companies have been moving that way anyway while making the office a less inviting space to visit with things like bench seating and "open offices" with no assigned spaces. Companies that develop actual stuff will suffer if they go full work from home. Something is lost when there is not at least occasional face to face contact, and my observation is that cooperation across functions is poorer in the WFH environment.
Also, eventually people will figure out that WFH is not necessarily a benefit, it's a way to push the cost of your employment back onto you.
