A man might look at the same photo and find the woman attractive which will lead him to make positive assumptions about her personality (confirmation bias again), or conversely find that she resembles a crazy ex girlfriend which will irrationally make him feel negatively towards the woman. These richly varied but often illogical thoughts and experiences are what drive humans to the various behaviours – good and bad – that characterise our race. Desperation often leads to innovation, fear leads to aggression, and so on.
For computers to truly be dangerous, they need some of these emotional compulsions, but this is a very rich, complex and multi-layered tapestry of different concepts that is very difficult to train a computer on, no matter how advanced neural networks may be. We will get there one day, but there is plenty of time to make sure that when computers do achieve AGI, we will still be able to switch them off if needed.
