Would that it were but in my experience long meetings have been replaced with longer zoom meetings. You squeeze in more work because you're already at your desk but the communication has gone down because there's even less focus.

Of course it varies from team to team. I don't see any evidence of widespread improvement in skill. Although I think there's been some value in higher slack adoption so the barrier between offices has lowered while intra-office is worse. At least that's what I've personally seen.
