Virtual meetings and broadband reliability have pretty much killed business travel and has made serious inroads in foot traffic in professional offices. Accountants, lawyers, financial planners, etc. have all reported a sharp drop in clients coming in rather than meeting virtually. It's so nice that people don't have to stop their day, drive to the professional's office then drive back. With the virtual meeting the "wasted" driving time is gone, the interruption in the day is much less, no parking issues, no fighting traffic it just goes on.
With churches like the RC and Orthodox where receiving communion is the point then zoom doesn't work. That was something that even struck me as a child the few times we went to weddings at a RC church, I was impressed with how they seemed to participate in the mass rather than just sitting and being talked at and the whole communion act seemed more like worship than answering canned questions at the WT study. The KH meetings always had a very low personal investment as far as I could see.
