Thing of the past
Work in offices was a thing because we didn't have a technology that enables remote working and not everyone could afford a computer nor employers wouldn't trust an employee with an expensive device.
We live in a completely different world now. Only problem is that we let rich funds exploit the housing market, so they were building flats with investors in mind rather than people living there, so many people don't have a dedicated area in their home where they could carry on working.
I think we may be looking at a hybrid situation, where employers will be renting out offices closer to workers or we may see more co-working spaces (shared with many companies) where employees would go instead of their company main office.
