In the long run that will certainly happen but it will take a bit of time before such company inertia is changed. I’m just hoping for any countervailing force which keeps them there:)
No few companies have moved IT support functions out of NYC to surrounding areas (or even out of the area entirely) in the wake of 9/11 - the current pandemic will hopefully accelerate that.
I am of Robert Heinlein’s opinion - NYC and the other coastal cities are far too concentrated and vulnerable targets for our enemies. We *need* to decentralize from them, and now the technology not only exists for work from home but the deadwood older management cannot deny that it works any more.
