Meeting virtually just isn't as efficient - at my company we've had several instances where we were trying to work stuff out with clients over Teams over the course of multiple days/weeks, and someone remarked that if only we could get on a plane to X country we could have it all sorted in a day. I think we'll see a drop in people being sent across the country for a 3 hour meeting... but I think many businesses will agree it's more cost-effective to do things in-person in a lot of cases.
