I think GNU and open source will have a long-lasting impact on science as well. One of its contributions is that now we can point to computer science (esp. in areas like cryptography) as an example of an area where code and methodology etc. are shared openly, setting an example for scientists in more traditional areas, like chemists and biologists, in becoming less closed-fist about their experiments. Going forward, I think we should also emphasize "free data" practices.
