Every few decades there are fundamental noticeable differences in the world, compared to a similar timespan previously.
To me, 2020 onwards has been the start of something new. But something that was discussed *for decades*. Back in the late 1990s / early 2000s there was a view that - since everyone was going to to be online - why couldn't we just WFH? Of course it doesn't apply to every job, but even back then there were theoretically a fair number of jobs where it would have been possible.
A lot of excuses were used over the subsequent years as to why it "wasn't possible" for employees to work remotely. But the main reason put simply was trust. Employers didn't trust employees to do a full day of work unless they could be monitored and supervised. A lot of middle managers realised they wouldn't be needed under this arrangement. The first Covid pandemic gave a lot of them a simple choice: let your workers WFH, or don't have any staff to do anything. They realised which one was more economically viable quite quickly.
The idea of commuting to an office, wearing a suit, commuting back... to do work you could do from anywhere is just archaic. There is literally no need for many people to do that anymore. We're not going back to it either no matter who thinks it's a good or bad idea. The market for work and staff is no longer whatever employers think is appropriate. You want the best employees? You're going to have to be more flexible and offer WFH.
