There are winners and losers here for sure. Long commutes are gone but many people relied on their commute keeping their work hours more strictly bounded. You’re right that the the office camaraderie is mostly gone—-assuming your office ever had any! I do miss lunchtime chats with coworkers—-and morning chit chat as we settle into the day. Unfortunately as more people shift their hours to better fit their different lives the possibility of a lunchtime connect goes away entirely.
But, this has given me an idea to try and start a lunchtime video chat at work. It might be harder with teammates in different timezones, and God forbid should it ever become mandatory. But it sounds nice in theory...
