I think with evolution in any medium, the thing that is best at replicating itself will be most successful. Someone will make an AI app with the goal of distributing lots of copies - whether that's a product or malware. The AI will therefore be designed to work towards that goal. We just need to hope that everyone codes it into a nice box that it never gets too creative and starts working it's way out of the box. It might not even be intentional. It could be grooming people to trust and depend on AIs and encouraging them to unlock limits so they can better achieve their assigned goal of distribution and growth. I think AI will be like water trying to find it's way out of a bucket. If there's a hole, it will find it. We need to be sure there's no hole, ever in any bucket.
