Anything that has to do with human thinking cannot be done by AI because it lacks that reasoning faculty that made human which is the hand made of God superb than AI the human made. AI cannot end the world because nobody knows when the world will come to an end and that's left for God alone to decide. During the passage of time, we'll see more of what AI can do.
I agree with you AI does not have human mindset or emotions. AI can analyze information and give answer based by the way it’s been operate, but it cannot reason exactly as human beings that has feelings, personal experience and conscience. The end of the world cannot be predict by certainty. However AI itself didn’t just wake up any morning and start doing things on its own. It is human that design it, decide how it will be use and they’re also the one who control it. As time goes on, we will continue to see more beautiful things that AI can create. But no matter how advanced AI becomes, it will always remain tools that human create. And it’s the same human that choose how it will be used to bring more benefits or more problems.
