AI, to me, is a duel edged sword. Could be very good, could be very bad.
It would be a wonderful thing if they could cure Alzheimers and AI is used for a good purpose. It's probably one of the most heart breaking diseases there is. I don't know if it is more prevalent now. People used to die younger.
Yes I see AI as a dual edge sword as well. How many jobs is it going to cost? I've read that AI will replace even doctors, nurses and surgeons. When AI is able to replicate itself and teach itself new tasks, we are in trouble. It will override our intelligence and most every aspect of our lives. Militarily it could overtake our own army, navy, air force and marines.
So what is left for every day people to do as far as jobs -- certainly everyone can't go into AI, especially when AI will surpass human intelligence.
Finding cures for cancer, Alzheimers, Parkinsons, and other diseases is obviously a plus, but at this point in time I see a dangerous downside. AI will be able to know what we are thinking and react before we get a chance.
Do we really want to go down that slippery slope??
