Yes, the point I was replying to was basically referring to unintended runaway modifications that could be disastrous like horror movie level. Chickens that can’t walk is not runaway because… well they can’t run, lol, so they also can’t breed. If humans died tomorrow, thoses chickens wouldn’t be far off.
That said, I support lab grown meat research. So we can stop with the chickens that can’t walk. But that won’t save the dogs that can barely breath due to selective breeding.
