The importance of those slippers is tied strongly to their rarity. So little survived from 5000 years ago that almost anything from that time is valuable. By comparison, we'll create more data in the next ten minutes than entire centuries from our relatively recent history. Lots of stuff is getting preserved in lots of places with substantive redundancy for virtually nothing. Your slippers today are likely to be more valuable than the near-infinite troves of documents and photos and whatever else.
