That was 10 years ago. The further we get from “the 1900s” the broader the term will become to include the whole century, much like the 1800s is 1800-1899. I imagine in another 10-20 years it will be more and more common to see this shift when referencing past events.
Not to mention that COVID season is already starting up again and with things like long COVID still not being understood fully it’s absolutely ridiculous that people are being herded back into an office.
