Isn't this just the automated version of "anybody can invent crypto they can't break themselves"? It doesn't sound like the neural nets were provided with any high level cryptanalytic primitives. Just basic math and left to bodge something together. I can't imagine it would be easy to hill-climb towards an understanding of the why behind crypto. Algorithms that work look a lot like ones that have glaring flaws - but those flaws only glare if you know the right way to come at them.
