This is just handwaved nonsense. You're telling me that prior to video calls, people didn't cultivate relationships on non-video phonecalls? Just total nonsense.
Building relationships is always easier face to face, whether it's a business, platonic, or romantic relationship.
Sure, but how does that relate to video calls? They are by definition not in person, camera or not.
The opposite is true as well. Why show up in person when you can be effective remotely?
I feel like we're just saying things now though.
