The thing that strikes me about the 'paperless office' as it was hyped isn't how much paper use was reduced, but what was enabled or sped up by computer databases or the internet to work with a head office. Consider how restricted most mail order companies would be compared to the modern market if they could only communicate with their customers, suppliers, logistics and other partners via phone/fax/physical mail, and they either had one central records department or the difference in efficiencies handling a network of local branches/franchises.
That leads to pondering if we're actually seeing a similar shift today with AI.
