The most popular websites off 2006:
- Yahoo sites!
- Time Warner Network
- MSN-Microsoft Sites
- Google sites
- eBay
- ask Jeeves
- Myspace
i.e. the most popular sites can and will eventually die, several have in the past 20 years....
For broader context:
The oldest non-consumable product is the cymbals made by Zildjian, which are ~400 years old.
The oldest continuously made product of any kind is German beer going back ~1000 years.
The oldest continuously operating library is ~1500 years old.
The oldest continuously published / in-use text is the Rigveda collection of Hindu hymns which is ~3000-3500 years ago.
The oldest information in general that has been passed on continuously are the oral stories in Australian Aborigine culture, known as Dream Time stories that accurately describe volcanic activity that occurred ~10,000 years old.
And we first start seeing modern behavioural traits in humans (like complex tool use and art) start appearing around ~100,000 years ago.
So yeah, eventually those sites will probably die, the mmlongeat last things are usually religious, not corporate, with the only caveat being that it's always possible we end up in a sci-fi like future where humanity manages to pull up from it's accelerationism and stabilize into a longer term society.
