The second thing that will be free is a complete curriculum (in all languages) from Kindergarten through the University level. There are several projects underway to make this a reality, including our own Wikibooks project, but of course this is a much bigger job than the encyclopedia, and it will take much longer.
In the long run, it will be very difficult for proprietary textbook publishers to compete with freely licensed alternatives. An open project with dozens of professors adapting and refining a textbook on a particular subject will be a very difficult thing for a proprietary publisher to compete with. The point is: there are a huge number of people who are qualified to write these books, and the tools are being created to leave them to do that.
I just wanted to add one little note to today’s post, based on an excellent philosophical question Diana Hsieh asked yesterday about my views on free knowledge. While I do, in fact, think that it is wonderful that each of the ten things I will list will be free, the point of naming the list “will be free” rather than “should be free” or “must be free” is that I am making concrete predictions rather than listing a pie in the sky list of things I wish to see.
