Colors, great. But right and left have nothing to do with conversation. There are plenty of other associations that are usually in place, like username and time. There's no benefit to adding paradigms that are not analogous to the situation.
Discussion
If you are in nature, how much text do you see? Zero. If you are in nature, how much visual placements of things that do you see? All the time, all day, every day, Think about it. You see the sun on the left side of the tree and the shadow on the right side of the tree. You see dangerous animal on the left side of the river but you see food you can hunt on the right side of the river. If you walk down the wrong path away from family, you will get lost and you will die. It is literally difference between life and death. If you drive on the wrong side of the road you crash and die. There are many things that do not have sides, but we make them have sides. Like New York being on the right side of the map. You can flip the map any way you want. There is no left or right politics. It's just something we use for easier placement, easier understanding and faster processing.
Yes, we can use text and timestamps and all that. You are 100% right, yes we can. But we process visual placements even on a screen 60,000 times faster because our brains do not change just because we're using screens.
Hope this helps
It doesn't help. It's still extra data that doesn't really add a benefit. There are plenty of other visual clues to give, that are not left-right paradigms.
