He is remembered because people took the tablets and transcribed it from medium to medium. Wrote books about it. Made movies about it. And created internet articles about it. If no one moved it from tablets to these new mediums, he would not have been remembered.

Tutankhamun is a great example of this. His name was forgotten. His existence forgotten until they discovered his tomb, read the tablets, and then transcribed knowledge of his life to the modern medium. His memory now exists because we transcribe and communicate this information today.
