I'm not sure what that's supposed to mean.
Read
Dr. Keith's post. Maybe that will help you understand what it means.
For most people in most places, life has returned to normal. Lockdowns are over. Kids are back in school. Travel is overwhelming the airlines. Masks are rarely required anywhere. Effective covid vaccines and treatments are available to everyone. Rates of death and hospitalization are down dramatically from the peaks. Covid might never disappear, but it has become something we are living with.
You have indeed missed the point: Pretending that the pandemic is over doesn't mean that it's over. Some people know that. They know about infections and deaths, too, which is why they aren't fooled by 'life having returned to normal'. As for travel being overwhelmed, could this have something to do with it?
Labor shortages made it even harder for airlines to recover from routine events. Overambitious carriers trimmed their packed schedules to give their operations more breathing room. Overwhelmed European hubs capped passenger numbers. Even airline employee travel perks were scaled back.
(...)
Airlines canceled or delayed a greater share of their flights compared with 2019. Thinner staffing levels and training backups meant they had fewer crew members to step in when scheduled employees like pilots reached federally mandated workday limits.
Airlines’ chaotic summer is over. These 5 charts show how it went (CNBC, Sep 9, 2022)
TSA screening lower in 2022 than in 2019, at least until September. See article.
As for the effectiveness of vaccines: They are very good at lowering your risk of dying and getting seriously ill, but they still don't stop you from getting infected. And many people still get seriously ill and die. Lowered risk ≠ no risk. Dr. Keith survived, and since he mentions nether hospitalization nor sequelae, I assume he is one of the lucky ones. Even in children, Covid-19 is the worst killer of all infectious or respiratory diseases:
Findings Among children and young people aged 0 to 19 years in the US, COVID-19 ranked eighth among all causes of deaths, fifth in disease-related causes of deaths (excluding unintentional injuries, assault, and suicide), and first in deaths caused by infectious or respiratory diseases.
The risk is considerably lowered by vaccinating kids, but many countries won't do that. In some countries, parents have to take them abroad to get them vaccinated. Not everybody can afford that.
And some parents just don't want their children to catch and spread the disease. Sometimes because they themselves may be immunocompromised, sometimes because other family members are. (And a few probably still consider the well-being of fellow human beings. Yes, I know!)
Compared with the peaks, the numbers are down, obviously. But 'we are living with it' means that some are dying both with and of it, which influences people's beaviour. So does pretending that it's all over, but obviously not enough, in the opinion of some people, and not enough for downtown to get back to normal, which you seem to be in denial about even though downtown business and transrport was the problem mentioned in the OP.
As to the original question, office workers have discovered that they like not spending hours a day commuting, with all the associated expenses, and employers have learned that they don't need to spend big bucks on expensive real estate. That's something that won't change, even if the covid virus suddenly somehow disappears completely.
And some office workers have discovered that it's a good way to avoid the infection.
"If the covid virus suddenly somehow disappears completely," those office workers will return downtown. As long as the pandemic isn't over, they will prefer to work from home.
Does that make it clear? If it doesn't, look at the numbers! I
posted a couple of those in this thread.
