Guess what, those are the worst odds in the book.
This isn't a hollywood movie set where miracles happen. In reality, each spawned child is likely to simply re-create the mistakes of the past generation.
1 Person spawns 6 kids, say 1/5 are female, each one of them 4-6 more.
Within a few generations, you have 50 people on welfare each dragging 4 carts of frozen waffles and canned cheese out of the store. :fuuuu:
