I was just seeing a documentary about him (the Internet actually) by Werner Herzog. It was the first time I had heard about Xanadu or Ted Nelson. His ideas were quite radical from what I know as the Web. And I got to thinking how the web might have been had Xanadu become mainstream.

But then I opened the Wikipedia page on Project Xanadu, it's second paragraph is:

> Wired magazine published an article called "The Curse of Xanadu", calling Project Xanadu "the longest-running vaporware story in the history of the computer industry".[2] The first attempt at implementation began in 1960, but it was not until 1998 that an incomplete implementation was released. A version described as "a working deliverable", OpenXanadu, was made available in 2014.

So... I don't know what to make of it.

It's basically as if he proposed a teleportation device, but couldn't deliver any of it. And when Tim berners Lee build an airplane which everybody started using he starts complaining on how much better his idea was. In recent years he's only been doing that last thing.

It was proposed in the 1960s as per Wikipedia.
