But the book is made up of text (printed letters). That's closer to memory, than software (what is saved in the memory).
Discussion
software is stored on persistent memory ( hard disc ) just as text is stored on persistent paper (and ink)
The memory (as in ROM) is the virtual environment that we create in computer eg Runtime .. Or in our brain in case of a book/text ..
The parallels are slightly hard cuz our computers are quite primitive - compared to our brains .. hopefully AI based computing ( not AI models ) shall reinvent the computers and make their run time simulate with our brains ..neural computing
The key is to understand " what is STORY" .. cuz hardware and software are fungible means to tell a story .. they are only an improvement over text and book ..
The real thing is to fathom what makes a narrative..and how we comprehend it ..
