Currently, when non-modified crops have offspring with GMOs, the result is usually unviable (because that's what GMO owners would like) or distributed accordingly to Mendel laws. If modification is maladaptive, it's going to disappear. If it's cosmetic, it's probably not going to dominate. But with gene drive, virtually every offspring will be modified to, and their offspring too, leading to modification of the whole species to monoculture gene.
