I think the computer science department has used internet really well with the open source projects. But, the same can't be said of most experimental sciences. In life sciences, we sometimes wait a few years from when an idea strikes a researcher to academic publication. An open-source collaborative approach could have immensely sped up progress. Not only that, the academic papers often describe only the experiments that succeeded. Anyone trying to reproduce the result will make the same mistakes as the original authors. What a blatant waste of human brain hours!
