one way I would like to see ai change or save the world is doctors/surgeons being replaced by ai surgeons. the reason I think ai would be better for this task is because ai would be a lot more accurate and a lot less of a chance of things going wrong or mistakes being made by a human surgeon. I also think that robots/ai could make mistakes, but they would not be anywhere near as prone to it as a human surgeon. The only flaw I could see is if there is a surgical case that requires human experiences and/or a humans level of common sense
