The article I subscribed to WIRED for.

"It wouldn't take millions of dollars. I estimate something like a three- to six-man, monthlong effort." I instinctively factored this prediction in my head, because I recognized the code in which the Xanadu programmers speak of the future: six months.

My thoughts (posted elsewhere):

i am of course fundamentally opposed to a lot of the core of xanadu because I am very anti-copyright and anti-capitalism. also we have a damn good citation system on the web and bullshit citation chains still manage to spread. i think the idea that people en masse would comply with a system that tries to enforce perfect citation is hopelessly naive. like any Great Libertarian Project, the idea doesn't seem to be aware of its own weight or ramifications, but instead simply standing before itself in somnambulant awe
