Digital is also shitty for long-term text storage, frankly. Data formats change constantly, software to read stuff changes constantly, disks go bad, the power goes out, and so on. The only thing that comes close to rivaling the durability/reliability of paper kept in a dry dark place and free of bookworms is clay tablets, and they’re a real hassle to make and lug around. Archivists know that if you really need to preserve a text you print it on paper and store it appropriately.
