Things have improved but we still don't really have the like whiteboarding (or whatever) together in a conference room. I agree that it's partly the lack of tools--maybe VR will help although this whole "like being in the same room" notion has been around for a long time and it hasn't been cracked.

Some of it is also cultural. If you're not going to have drop by conversations and other serendipitous meetings, you need to be more disciplined about having those conversations anyway even if they wouldn't have historically risen to the level of sending an email or making a call.
