Plus if remote work really takes off, there's no need to crowd all those people into the downtown cores of a few cities anyway. It'd shift housing demand to cheaper, more naturally desirable locations.
What'll happen is that a few firms with ineffective cost structures will go bankrupt, a few major cities will become hollowed-out wastelands the way NYC was in the 1970s or Boston was in the 1950s, and economic growth will pick up in other areas, with new startups and new desirable hubs.
Except in SF or NYC, there aren't that many desirable "different locations" left. Which is why freeing up the poorly used space in city centers can be a net positive for society rather than keeping to maintain these white elephants.
Have you heard of sunk cost fallacy?
