Paradoxically, I think that the post-crash recovery will be a great opportunity for WeWork (if they survive). My guess is that many companies will outright close most of their branch offices, shifting people / teams that want or need to be in an office to coworking spaces.
This movement will also have reductive effects on carbon emissions, so despite the coming carnage in commercial real estate, it's the right direction. Hopefully a lot of that square footage can be converted to residential, because there is still an affordable housing shortage...
