Almost 10 years ago, we created the Science 2.0 movement, which was geared toward modernizing science collaboration, publication, communication and participation. And then...not much changed. Science is, at its heart, competitive and there is no benefit for most scientists in collaborating. The person who puts something all together at the end will win a Nobel Prize and everyone else will get nothing.
On the smaller scale, everyone who wants government funding is competing for it, so collaboration will only help another lab avoid expensive mistakes or get to a result sooner. Science 2.0 was greeted with enthusiasm...for someone else, anyway.
