Because we have a hopeless understanding of the vast differences in minds found in the chimp troupe. Leave alone the consequences of such huge variation. As soon as one chimp has a realization about its mind, it then thinks all the other chimps should and can have it too. Which is as dumb as a mango tree discovering it can produce a mango, and then walking around encouraging banana trees to try to do the same. The banana tree will fail no matter how much it studies the mango tree. It might even forgot it is capable of producing bananas.
