I'm glad I am retired, email was the primary method when I worked. It's still the primary method for me today. I use SMS for a few things. I dislike instant messaging for anything.
The article mentions video, until recently I never considered it, aside from occasionally talking with family. Now it seems meeting are now being conducted via this medium. I had a Department meeting just a few days ago on Zoom.
When I said retired that meant from a paying job. Now it's all work, no pay.
