At the session on Tuesday, computer scientists talked about how new payment technologies could increase individual control over money. For example, if people adapted the so-called ledger system by which digital currencies are used, a musician might potentially be able to sell records without intermediaries like Apple’s iTunes. News sites might be able to have a system of micropayments for reading a single article, instead of counting on web ads for money.
.. “Ad revenue is the only model for too many people on the web now,” Mr. Berners-Lee said. “People assume today’s consumer has to make a deal with a marketing machine to get stuff for ‘free,’ even if they’re horrified by what happens with their data. Imagine a world where paying for things was easy on both sides.”
.. Mr. Kahle’s Internet Archive, which exists on a combination of grants and fees from digitizing books for libraries, operates the Wayback Machine, which serves as a record of discontinued websites or early versions of pages.
To make that work now, Mr. Kahle has to search and capture a page, then give it a brand new web address. With the right kind of distributed system, he said, “the archive can have all of the versions, because there would be a permanent record located across many sites.”
.. “The web is already decentralized,” Mr. Berners-Lee said. “The problem is the dominance of one search engine, one big social network, one Twitter for microblogging. We don’t have a technology problem, we have a social problem.”
