I've been expecting "peak office" for years now. Offices originally existed to contain paper records. Look at pictures of offices from 1700 to 2000. You'll see much paper, and much paper storage. That's dead. If everybody in the office is using a screen and keyboard, the classic function of an office is gone. It may still be useful as a social business space, but the age of the clerical plant is over. (Outside of some Government agencies.)
