So I am re-watching Ds9 and I am up to the big reveal when we notice that Dr. Bashir is a changeling. So it made me wonder how smart the Founders must be, either on their own, or with the dissemination of knowledge throughout the great link. Being able to look like and sound like someone is one thing but being able to be a Doctor is quite another. I get that since they engineer their own subservient solids then they must know about anatomy but I still wonder how long it took them to learn, at the very least, every medical thing Dr. Bashir knew? Then you might say, maybe that guy was just pulling a "catch me if you can" type thing and faked it while having his underling Doctors on the station take care of most major surgeries, but that doesn't seem like something the Founders would do. So I guess my question is are the Founders just that smart to completely do anything the person they replaced can do, or are they just really well trained intelligence agents who get by on generalized knowledge on who they replace and what they are doing?
