I don't want to be a wet blanket, but even after a vaccine is distributed I am not at all confident that things will ever return to normal.
People have been terrified of this virus for months and for many, it will be harder to switch off that terror than it would be to just turn off a lightbulb. They'll find out that it is not 100% effective, or that the virus has mutated, or who knows what.
Another factor is that many/most small businesses will have gone under or will be on weak financial footing. And as for larger businesses, people are used to working at home and will balk at the idea of going in to an office to work. So, no more business districts in cities, no more commuting. People will just email their work into megacorps, wherever they may decide to be. Cities will become empty ruins, and rural areas will be flooded with city folk. None of this is consistent with returning to normal (IMO).
OK, maybe this is a worst case scenario, or a really, really bad dream! But I just don't see us reversing course back to where we were before the pandemic, any time soon. I sure hope I am wrong.
