About 15 years ago, I won a phone in a contest. Last week I tried to find information about it, but I couldn't. No AI, nor Google could find anything the contest I won it in. When people say "the internet is forever" that can certainly be true, but it isn't for everything.

That reminds me - my wife had a friend who was killed by a shark (no joke). There were newspaper articles, but Google has completely forgotten about this and the newspapers are often behind a paywall, changed their URL's or simply the article vanished from those sites as well, which certainly doesn't help.
