All remote work did was showcase people can in fact rebel against the status quo when the inertia associated is entirely self-inflicted.
I think that's an overstatement. I've been more remote than not for close to 20 years and 90%+ remote for close to 10.
That said, there is some point in time before which companies would have had to largely shrug and tell people that they had to stay in the office pandemic or not. (Which of course many jobs and professions basically had to anyway.)
That said, I've been a professional programmer for all that time, which in my mind is practically made for working remotely. It's definitely taken longer for some other industries to be as amenable, which I believe has been due to the people in charge, not the profession.
I agree that general inertia has something to do with it, but that's a terrible reason to accept the way things are.
Also I would bet that the amount of people who prefer remote has gone up drastically since 2019, both due to exposure to it, and due to covid isolation shifting people's personalities.
