For a basic non-engineering example, think about B2B sales. How much of a typical B2B sales cycle involves phone calls and emails and video meetings versus how much involves in-person meetings? Hasn't the first part of that more or less been "remote" since well before the virus?
To an extent, I think a large part of this view, as other comments have noted, might involve things like expensive office leases, etc., and to a certain mindset - realizing that a company doesn't necessarily need much of a physical presence highlights many varieties of poor longterm decision-making.
