Then I noticed that e-paper is window to knowledge that allows me to look in but never allows my mind to enter. There is cognitive wall between myself and the things I read.
Reading physical papers and books and storing them is concrete memory palace technique. Writing notes on them, underlying, leaving coffee stains and folding corners, adding sticky notes etc. is concrete physical creation of of a memory palace. It helps to arrange, retain and absorb knowledge with spatial associations.
When I store paper I have just read into a stack of papers, or put it into a folder in a bookshelf, it's stored in a spatial space that helps with remembering and recollection just like memory palace memorization technique. If I look at the paper years later, just quick glance brings in the associations. E-paper tablet is just the same tablet every time.
I still use tablets and computer to read fiction and skim abstracts. If I have to fully learn and think what I read, I print it out.
