I'd say yes. Do you think the ideas that came from the Manhattan Project didn't exceed that of the best individual involved?

Or for a more extreme example - consider the totality of human civilization as an example of groups of humans working together. People like Einstein and Hawking wouldn't have been able to have had the ideas they did if they were dropped in 20,000 BC. The knowledge we have now isn't simply the work of individual animals with extraordinary thoughts, it's the result of large groups of these animals working together.

Now certainly the benefits in corporate R&D labs don't come anywhere close, but I find it hard to believe that they simply drop to zero.
