> real interaction between people where people perceive all these tiny non-verbal signals like changes in posture, gestures, mimics, breathing

I dunno. I sometimes feel like many of those things just make communication more stressful, accident-prone, and overloaded. Too much to overlook, too much to accidentally let slip, too much to process besides the content of the massage... Just too much.

Voice is pretty useful to me, but for the most part taking body language out of the picture is a burden relieved for me. I'm happy to be represented by my words and voice alone.

> you can actually point a colleague to something with your finger

That's a great thing when it works, but it's not really a given in person, either. I don't see well enough to identify most objects when someone points from across the room anymore, let alone to read someone's screen in the tiny font sizes the average person uses or cope with light mode.

A link to source code or a reference to a file and a line number is way more flexible in terms of letting people meet their own needs for contrast and sizing, clunky though it may be. Same thing for digital whiteboards; some people essentially can't participate in conversations centered on a physical whiteboard.
