I remember seeing a paper (https://pmc.ncbi.nlm.nih.gov/articles/PMC4274624/) that talked about how physical writing helps kids learn to read later. Typing on a keyboard did not have the same effect.
I expect the same will happen with math and numbers. To be fair you said primarily so you did not imply to do completely away with the paper. I am not certain though that we can do completely away with at least some pain. All the skills I acquired usually came with both frustration and joy.
I am all for trying new methods to see if we can do something better. I have no proof either way though that going 90% excel would help more people learn math. People will run both experiments and we will see how it turns out in 20 years.
