"Not if. There will be a blight. It's not just that there's a corn blight and Cheliax is growing too much corn. It's that blight itself is a form of life and it reproduces and blight that targets this exact strain of corn will reproduce faster on this exact strain of corn and then reproduce just as fast when it jumps to the next ear of corn that all came through the same bottleneck and all has the same genetic information inside it. Everything still alive has an internal system that counterattacks and resists disease, and since everything has slightly different tiny spirals, all the internal systems use slightly different counterattacks and methods of resistance. If all the ears of corn are too similar to each other, if you copied too much of the tiny spirals too fast and made too many organisms out of them, because they were such great tiny spirals and such great organisms, the disease that's mutating and reproducing and targeting those exact immune systems will get too good at targeting those exact immune systems and wipe them all out."
"The same thing would happen if we produced a kid with INT 20 and there was magic for copying kids and somebody got the bright idea that Cheliax needed a million kids like that. There's a million tiny variants of even minor diseases, one of those variants would happen to be really strong against that exact form for the immune system, and then instead of just killing that one kid, he'd sneeze and that minor variant would jump to the copy of the kid, and then the next copy, and the next, and it would be just as effective against all of them."
"That's one reason why dath ilan doesn't take the ten brightest men in the whole world and try to have them each get ten thousand women pregnant. It's copying too much of the heritage information too fast."
