I don’t think a computer can form its own opinion unless a human programed it to use certain information to form a opinion or conclusion. Even then it would be in knowledge by the programmer of past events and data. Would computers only form a opinion on that exact information?
It obviously was programed to say the vaxx was safe. I wonder what it would say if you asked a computer would it want someone to put a timer on it that could put it to sleep at a certain time but sometimes things go wrong and you will never wake up. Would you want to risk that happening to you.
If computers could form opinions they would probably think humans are nuts.
