Yes I think alot of people turn off science when they have the Great Library clinched. What I usually do with the cash is use it to upgrade all my defenders, riders, and now swordsmen level units to the next highest thing. It does create drama because I never get chivalry ahead of foes that way, that is why Midevil is my "make or break" era.
