But everything has a cost. If you've been going full scientist specialists, enough so that you're getting all these great scientists, then you're sacrificing in other departments. Im currently in a game where my neighbour, Poland, is yonks ahead of everyone else scientifically, but my culture is more powerful. Powerful enough to start having influence over him if I full specc'd it. Also, I looked through his cities, and he is by far the leading power in technology, and I didn't notice many of the Great Scientist wonders. It was more commerce & lack of war that was propelling him.
