Great questions and what is this not a hot topic. Sentient AI scare me for sure. They better not let it talk to any other AI connect to the internet. When Face Book tried that the computer stated to form it’s own language. They were so scarred they had to unplug it. We need some type of regulate and it’s enforcement that prohibits this behavior and studies it completely. The Chinese and Russians, North Koreans, Iranians etc. scientists are more doing these same experiments. To what end? That’s the real questions. Anyone want to fight a sentient AI? Terminator ring a bell?
