Remember the "paperless" office, how computers were supposed to eliminate paper? Yeah right! Sure, there are some paperless offices, but that is not the norm. Most offices go through more paper now than they ever did. That paperless office was supposed to be a reality back in the 90's. So much for that!
The role of paper has changed. It used to be the primary, permanent storage medium for information. Now it's more of a temporary medium to store text while it's in process. After the process is complete, the paper is often destroyed. Still, paper hasn't gone away.
Similarly, it's going to take much longer than anyone anticipates, to replace office workers with automation. And similarly, the role of office workers will change, and might even grow.
