The Xanadu proposal dates from the mid-20th century so it includes a quaint assumption from that era: people expect to be paid for the work they do. What, people are supposed to spend hours typing at a computer for no payment in order to make some billionaire even richer? Who would do that? It's nuts.

Yes, if Xanadu had taken off people might have had to pay a little to view its content. Just like we used to pay for books, records, movies, magazines, etc etc etc. It wasn't so bad -- those things were mass entertainment, not just for the rich, and they were certainly not a death knell for communication. I don't know how you came up with $10 to view a web page. When Nelson proposed Xanadu, mass market paperback novels -- hundreds of pages -- cost 50 cents. Kids (like me) could easily afford them. They were cheap because there was a huge market -- so communication could flourish.

It's not clear to me we are living in the best of all possible worlds. If the micropayments thing had taken off, it might have provided a way for large numbers of people to make some money by writing, etc. In our world, most of the money is made by a few corporations, and an increasing proportion of what's on the net is slop made by ... nobody.
