Teachers in the “olden days” before computers-was the job harder on paper?

My FIL was a teacher in the 70’s-90’s. Hubby and I were talking last night about the differences in our jobs. Husband said his dad’s job was harder because it was all paper that had to be graded and manually entered. I pointed out that I have to read the papers too, they’re just digital, and I have to manually enter my grades into our online gradebook. The conversation got me curious-if you’ve taught for a long time, do the digital assignments make it easier for you, or is it the same amount of work just in a digital format?
