You look at a multi-day Slack discussion with big architects and PMs without any progress... In the old days it would be a series of important meetings where those important people would be making important face and saying important sounding words. There would still be no progress, yet there would be the feeling like the progress is being made. Slack makes it so obvious. We're definitely going back to offices :)

This. Written communication makes it obvious that some people have nothing meaningful to say it have trouble with reading comprehension.

and even more important aspect - without offices there isn't jet-setting across the world nor fat expense accounts. The only thing left for CEOs and all the other execs is to actually do their job which is their least favorite activity and which they usually are hardly capable at performing.
