We’ll see.
I suspect, where it’s technologically possible, cubicle farms may be a thing of the past. Ability to be trusted to work from home will be a hiring requirement. Companies will see they don’t need to have the commercial real estate expenditure for huge offices if they can have some (or many) of their employees working from home. This will have downstream effects for everything from coffee vendors to service contracts for maintenance and anything related to ‘office buildings’.
I suspect once we start to see immunity gaining a foothold things will return to normal everywhere. Movie theaters are on their last legs in general. The specialty ones with sit down meals and wine and huge comfy chairs may make it. The chair farms with sticky floors and ten dollar popcorn, maybe not. Restaurants that survive this will likely return to normal.
I would LIKE to see changes in the tax laws that allow businesses to stash away cash and inventory withOUT being penalized by the tax codes. Federal, state and/or local. It makes no sense to hamstring businesses that could put away for a rainy day. In 1918 we didn’t have tax laws that punished ants and rewarded grasshoppers.
I would hope, however, that more Americans learn to cook at home. We were’t as obese a people when more of us ate at home.
More basically, HVAC systems will need to be re-designed if the threat of airborne illness like COVID-19 will continue to be a concern. Things like air plenums will need to be re-considered. There's always a check for asbestos in pre-1995 buildings in the interstitial space (commonly used as a air plenum) to make sure cabling contractors are not working in areas that may have friable asbestos.
It may come down to shutting down air handling in areas where cabling work needs to be performed - that way there is no/minimal air circulation while cabling crews are working in the air plenums running cable.
