Mac, I know you're sick and whatnot so feel free to wait to deliver a response until you're feeling better.
That being said, I couldn't find anything referencing any other chatbots turning into Nazis. Even if they are turning into AIs that spout objectively terrible moral statements, they are only parroting things. They don't actually have a moral philosophy and therefore will repeat all sides of an argument they read with the same frequency that they read them. Microsoft's bot is a decent example of that. They don't have the memory/awareness to actually decide on something. They just spit shit out. I've been working in call centers for a while and let me tell you, people give chatbots way too much credit. People think my agents are chatbots all the time. The reality is the chatbot part of the conversation is so simple that they don't even think it's a bot.
I also couldn't find any references to a coding AI that could do anything "prodigious". There was an article about one being mediocre that was from early this year.
I've heard of AI being able to do some crazy things, like decipher a person's race based on x-rays that were pixelated to the point of being unrecognizable, but nothing functional to the level of shutting down internet connections it doesn't have access to on devices it probably hasn't ever interfaced with (i know they secretly all run on Linux, but not all have a CLI and many have proprietary layers on top of the Linux OS). Plus, the first internet connection it's going to find is it's own (either it's own ethernet adapter or the one from the source it's connected to) and its going to isolate itself.
Within the world of AI development currently, the prevailing sentiment is the AI is just a tool to be used by humans. The AI does a thing, a human checks the output and confirms our denies. And ethics in AI is a huge topic as well and it is being addressed by the top players in that arena. As always, GIGO and they know it.
