What do you think has changed for good?

I don't intend this thread to be all doom and gloom, i suspect some will be positive :.
Work travel and office work. I used to travel two or three times a month, I suspect that will be two or three times a year in post covid times. Prior to this there was a real aversion to using the technology
Handshakes. Never coming back imo.
I really hope packed railway carriages are at an end but I doubt it.

Cash. Think it will be phased out.
I also think a lot of retail shops will disappear from the high street as people will continue to shop online.
Think people will be uncomfortable with large gatherings for a long time too!
