Not really. The office market is not that huge and the vacancies overall are also not that bad. It's not like every single office is suddenly empty.
On the flip side: where these offices are located, housing is extremely expensive, so you could transform some offices to apartments, pivot projects currently in construction and maybe even demolish some older buildings.
These headlines are just a sign that the current management class is utterly incapable of reacting to anything but "line go up". They can't understand that they can't exploit their way out of this for once.
