It's extremely hard to evolve anything significant in a single generation. History of science shows things take thousands of years. What speed up we get from tech and tools hides how unfit our own brains are for many problems people think they can handle. Theory of Bounded Rationality goes into it quite well. Also the Explore - Exploit tradeoff applies here. Depending on the type of Problems the group is solving different members are in explore or exploit mode. Some problems you need a whole lot of explorers and for others you don't. Welcoming anyone and everyone into a group without awareness of the current groups composition, what mode individuals are in, and what the real problems being solved are, is like watching what happens to a theatre company after they have finished a long run of a particular play.
