Some nations has gone over 1000 years and they still remember their origin story. History is not that easily lost and I don’t think the origin of bitcoin and satoshi will ever be lost.
In my country students are taught the history of money and how the country got to the current currency they are in now. We now have better ways to store and preserve history.
They remember it because it is taught in schools. These days people are not interested in reading long texts.They prefer to read short social media posts or videos on YouTube. In my country, history is a compulsory subject for children in primary and junior secondary schools because it is important to know the past of our land. Many people who are interested in Bitcoin are just focused on making a profit. I don't know how many of them have read the whitepaper or about the historical development of Bitcoin.
