I am surprised you didn't discuss how masks affect the most fundamental aspect of social interaction - loss of facial expressions. Our faces are so pivotal to social interaction, it is impossible to overstate.
With work from home you don't need a facial expression at all. Just close your Jira tickets quick enough, and surveillance software will ensure you are not doing anything funny in your working hours.
I guess it depends from a person to person. I actually find it relaxing, as being an Eastern European + an introvert I never really got used to American habit of smiling to everyone as a social norm. With mask I look less grumpy. :)
And also I think social interactions are constantly evolving process so, if needed, people would simply adapt to a new situation. Who knows, perhaps we'd start using our hands instead of facial expressions, just like the Belters did in The Expanse novels/series because they were limited by wearing space suits all the time.
