Offices were the 19th century’s answer to the need for centralized data processing, at a time when clerks entered information in ledgers using quill pens. Prior to that, the concept of an office was not known. Thus for 99.99% of human history we’ve existed without offices. It is implausible to imagine we’ll continue to employ a hopelessly inefficient and anachronistic device for another couple of hundred years merely because we’re too intellectually limited to realize we no longer need offices. At the very least, economics will ensure that to all intents and purposes, the office will vanish over the next 50 years. It would be faster, but we humans are a slow lot.
