I think there's a flipside to that latency, though - you may have to wait awhile, but once you connect, there's almost zero latency. When you're face to face with a person, you're not wondering if they stepped away from the keyboard to get a cup of coffee, or investigate whether their cat knocked over a christmas tree, or if their internet went down. You know their work didn't just page them with a critical error. The conversation goes much faster once it starts.
