True. However the inflexibility of the physical media (pen/typewriter+paper) forced people to think and plan before they acted. These days, not so much, and I can see the difference in approach when my kids are writing essays - back in the day we were taught to come up with a little plan, toc, etc before getting down to the details. Now my kids just spit it out without structure, then add bits an pieces here and there and call it done. Maybe they are taught the structural approach in scool, but the tools aren't helping.
